Fun and entertaining game! It's like a simplified version of Snake. There might have been another game I played on mobile years ago that was similar. Dashing felt a little clunky, I would've preferred to just dash in the direction I'm looking at, but I understand this would make it difficult to use when there is not enough space to move around, maybe make it move like on Gameboy games? You can rotate the character with WASD, but it you hold that direction, you start moving instead of just rotating around on the tile, just an idea.
Good work!
