The best way to add juice to your Unity game

Feel is a solution to provide on-demand game feel to your Unity game, with as little friction or setup as possible. It's modular, user friendly, and very easy to extend and build upon.

Packed with more than 150 feedbacks, it'll let you easily trigger screenshakes, animate transforms, play with sounds, cameras, particles, physics, post processing, text, shaders, time, UI, and so much more.

Initially created for the Corgi Engine and the TopDown Engine, it's a proven and battle tested solution that just gets the job done.

What's in Feel?

MMFeedbacks is a revolutionary system letting you trigger all sorts of effects effortlessly. Easy to setup, fun to use, it'll change the way you work in Unity.
MMTools is a library packed with various useful tools, and I thought it’d be nice to include it in the asset. Don’t hesitate to dig through it, it’s packed with surprises!
Included in Feel as a gift, Nice Vibrations is the best way to add haptic feedbacks to your iOS or Android game. You can learn more about it on its dedicated website.
Feel is packed with more than 20 demos, showcasing its various features. They showcase the various ways you can use Feel to make your games awesome.

Demo

Below is a small demo of some of the feedbacks included in the asset. Due to the current limitations of WebGL builds, most audio feedbacks won't work. This demo also doesn't demonstrate the URP feedbacks, the haptics ones, etc. It's still pretty cool!

Just scroll and click on any effect in the list on the left. Keep in mind that this will only show one example of use of each feedback. They can all be customized with tons of options, possibilities are endless.

You can also download the PC demo or the Mac demo.

More demos!

But wait, there's more! Feel comes packed with more than 20 demos showcasing all the great tools it contains. From small scenes focusing on a particular feature, to a complete and enhanced game of Snake, packed with feedbacks for each of its microinteractions, there's tons of contents to explore. Go play with them right now!

You can also check these demos as a PC build or a Mac demo, or even try out Chill Snake on iOS, or Chill Bowling, entirely powered by Feel. Their entire code and contents are provided with Feel. You could also have a look at this illustrated list of demos in the documentation.

MMFeedbacks

Feel comes with the MMFeedbacks system, which lets you stack and trigger feedbacks extremely easily. It's packed with more than 150 of them, ready to use. Most of them are completely autonomous and don't require any dependency, and some of them are dedicated to make use of Unity packages like TextMesh Pro, Cinemachine, URP, HDRP or PostProcessing. Feel free not to use them if you don't want to.

Here's a complete list of all the feedbacks included in the asset :

Testimonials

⭐⭐⭐⭐⭐
Absurdly High Quality
This asset both defines and nails the concept of a feedback. I've had this product for months and am still learning of new ways to leverage this powerful tool. Maybe lesser noticed by other reviews is the MMTools package, which is also included. Although this will mostly be appreciated by those who like to program, it's definitely worth mentioning. MMTools contains dozens of extremely well written solutions to common problems.

⭐⭐⭐⭐⭐
Fantastic tool! Even better support!
This tool is insane. It can do so many things to the point where it can almost be used for every core system in your game like audio, saving, scene loading, etc. The support from the developers in immaculate. Whenever I had a problem, the response time was within a few minutes, and I had my problem solved after a few email exchanges. This is an essential tool for any project!
- mcrump

⭐⭐⭐⭐⭐
Incredible, and incredibly well documented
This is a great asset, it adds a mind-boggling amount of ways to improve your game, all very well thought-out, modular, clear and user friendly. If that was not enough, the documentation is astounding, with complete and readable demo scenes, super clear videos, and a well-organised and detailed website. I am still in shock at how awesome this asset is.

Will there be updates? Will they be free?

Yes, updates are released very regularly.
All Feel and MMFeedbacks updates have always been free, and always will be.

Do I need to buy this if I own other MM Assets?

Some other assets by More Mountains include parts of Feel. Typically, the TopDown Engine or the Corgi Engine include MMTools and MMFeedbacks. Buying Feel would add Nice Vibrations, as well as all the demos unique to Feel. It would also give you an easy way to import Feel on its own in a project where you don't need TopDown or Corgi.

Because of this, buying Feel comes at a heavily discounted price if you own Corgi Engine or TopDown Engine. Simply visit Feel's webpage on the Asset Store, and if you're logged in with the same account you bought CE or TDE with, the store will automatically apply the discount. And remember that you never "need" to buy anything, it's up to you to decide if it makes sense.

Why Feel?

I strongly believe game feel (or juice, or microinteractions, or feedbacks, or whatever you prefer to call it) is one of the most important parts of game design. Making sure the player understands the consequences of their actions is the best way to make sure interactions are rewarding and engaging. Providing proper feedback when the player makes an action, or when something significant happens in the game is mandatory. Whether it's a screenshake, a flash, an object's scale bumping, or all of these at once, it will only make the experience more satisfying.

You can learn more about feedbacks in Martin Jonasson and Petri Purho's talk "Juice it or lose it", the wonderful "Art of screenshake" talk by Jan Willem Nijman, or my own talk about game feel and fast prototyping at Unite Copenhagen in 2019. Implementing these kinds of feedbacks isn't necessarily rocket science, shaking a camera is quite an easy task. But after working on tons of games and prototypes, I've found myself often going back to the same game feel recipes, and I wanted to remove as much friction as possible between an idea for a feedback and its in-game implementation. That's how Feel was born.
