THANK YOU! I really had a lot of fun working on it and I've definitely been considering making a more-fleshed out version of it.
Just out of curiosity, which bugs do you refer to?
The losing speed thing was intentional as a means of making a failstate for the game, but I did have some ideas for pressing buttons as a means to generate some speed manually or even increasing the speed you can get from bounces by timing a button-press.
Either way, thanks for playing and I'm glad you had fun!
