Overall, a pretty fun game with a very well-thought premise.
I think one of the better concepts, I have seen so far.
The use of certain colours and shapes were crude but sufficient to convey the purpose of each gameplay piece.
But,
- I think you should tweak the jump acceleration and deceleration further. Currently the character feels very floaty. Along with the sprite design, it looks like a paper doll. Maybe that is intentional. But jumping does feel tougher than it should.
- The instructions at the start were unclear. I was not sure if I was supposed to use a mouse or a keyboard, I only progressed after I tried a bunch of stuff and ended up clicking the black box. Adding an initial click here text box would easily solve the problem without much work.
- The trampoline component could have been improved further. The diagonal trampoline felt unnecessarily tough to control with the weird control scheme. Perhaps changing it to a vertical trampoline instead would have had the same effect but feel better for the player to handle.
- Overall game assets could be improved, but gameplay was fun regardless.
