This a pretty nice retro style game. The graphics are well drawn and I really enjoy the use of bright colours. It does a good job of capturing the ZX Spectrum feel you were going for. The audio is a bit limited but I can't comment on that as it might be part of the console limitations (I'm not that familiar with it).
The gameplay is simple but works well. I like how different objects in the room are used as platforms/obstacles (rather than some arbitrary blocks/spikes or something). The premise of being a guy who tidies up after guests at night is an interesting one, though I'm a little disappointed more wasn't done with it. It's a shame there was only one level but I understand the limits of a jam.
