It's fun with an interesting mechanic. It definitely seems like it's meant for mobile though, it's hard to quickly move the cursor to the other side of the screen in time.
A couple people have sujested I make this for mobile, I may try doing that but ive never done anything for mobile so I would have to learn. The end goal with this is for it to be like one of those old grindy flash games where you try to get every upgrade in the game.
If your target platform is web I'd recommend trying out how it plays with you bouncing off the wall instead of passing through to the opposite wall. Right now the biggest problem I find is not being able to react quickly enough when it switches sides on the screen.
