Obviously love the graphics and sounds.
Although this worked fine when you shared links on discord during the jam (not sure which browser I was using then but I think firefox), the final version just hangs on 'loading' for me (firefox). Works in Chrome, but massive (3+ seconds) lag during the game where it hangs for no obvious reason until you get through the first couple of levels then it seems OK - so I guess some background loading that should happen during loading screen but isn't.
I didn't realise it there was a move counter until late in the levels ,and I think it was a bit harsh to just wipe all progress instantly with no warning or way to go back. Replaying all the levels again seemed like a chore.
Also I had no idea when to use the powerups, knownig that they would cost money I ended up not using any of them. I'm not convinced that tieing them to a limited resource - in a game with instant permadeath - works that well.
