I like the concept and I would like the game if it weren't for a couple bugs.
Sometimes it pauses randomly. It will just pause and un-pause on its own and it won't stop.
Also, whenever I die, when the menu where you go to the "shop" or hit "retry" will come down for about a fraction of a second, and then it will automatically start another game. This way, I have no chance of actually hitting any of the buttons and not being able to go to the menu or shop.
I don't know if these things on purpose, but please fix.
I am playing on Firefox with an well enough computer.
