The rules are still unclear to me. Why do i die? And i would have liked it more if you could interact with the balls you already brougth into the game. It is a good concept though yet it still needs a lot of finetuning. A breakout where you drive around could be pretty fun^^
The concept is interesting but the execution leaves a bit to be desired. I feel like the player accelerates too slowly and also the invisible side walls are well within the play area which makes for a confusing death. It would also be nice to be able to hit the balls after they are in motion. It's a good idea though and something you could develop into a fun game after the jam.
Might have been better to force that or visibly mark the death walls to the sides.
