You did well.
The jazzy music and squishy sounds made your game very relaxing.
The particles were well done. The colours fit together very nicely. I liked the way you did the 3d effect. I also liked how you made the screen shake rotate the camera.
I liked how you made the coyote time work almost exactly like it works in cartoons instead of simply letting the player jump a bit late.
I wish I didn't need to read so much text in the tutorial. Also, I didn't like the lower gravity bonus because it made me go way higher than I wanted to. I'd prefer it if it were slower fall.
Other than that, your game was perfect. I have a good feeling Jonas is going to give you a free steam key for Will You Snail.
