Really simple but nice game, I like your use of the ZX-spectrum colour palette but perhaps searching for a ZX-spectrum colour palette on lospec.com will make the colours of the game fit quite better. I think letting a player know for the first time which level their in is a great idea but just once would be okay, it got really annoying having to restart a game and getting ready to play when the game pauses for a some seconds just to remind you again of the level you're in. It's all part of the learning process, I'm learning too. Besides these little issues great game
