Very cool game! It's fun the way the objective keeps changing, and there's just the right amount of juice to make the combat satisfying. The sound effects are well used and the music is great. The presentation is slick overall. Graphics are very readable despite the limited colour palette. I like the way it emulates retro games by having regions of the screen limited to certain colours e.g. everything on the same row as the timer turns green.
One minor complaint is the transition between rooms doesn't adhere to the 64x64 restriction.
