Nice, and about the right length for exploring the initial ruleset. (Except the red floor squares, which I saw on one level, didn't interact with, and then never saw again so I don't know what they actually do). I think it desperately needs an undo on death, and ideally should have player-triggerable undo/restart. Given the rest of the game, I was a bit dismayed at the end seeing that it had basically been a scored playthrough. If I'd known the moves were being counted, I would have played better! This won't apply to everyone, but there is a subset of players (like me) who really like knowing what to optimize for, so having a hidden scoring system be sprung on the player at the end is a bit of a betrayal. +1 on the arrow direction vs. movement direction mapping being a problem on keyboard. 95% of the time I was in a flow state and it wasn't an issue, but if I made a mistake I'd immediately lose faith in having the right mapping, start second-guessing myself, and make follow-up mistakes.
