What a blast! I could play 50 more levels of this! Just a few things:
- I think you should use a quick visual tutorial before the game begins.
- I think E is more comfortable to press than F, especially if we're going to mash it and move constantly.
- I'd begin with smaller, faster levels before getting a full house to clean.
I know you guys made this game in 48h, and that's impressive! It's got A LOT of potential to become an indie, arcade-like game! Huge congrats!
