Nice game! Got 4th place on the leaderboard, on first play through. :) I guess I then feel like I completed it, and don't want to play again. Not sure what to suggest as improvements. The game was enjoyable to play. It would be good if I didn't complete it first play through, I guess (and then I would want to play again to try to complete). Maybe if it felt clearer that what I needed to do to get higher on the leaderboard (time to complete?) was actually important, I might then go back and try to get a higher place on the leaderboard. Also, I guess there is always the possibility to add a meta (rogue like) set of unlocks/upgrades outside of the game itself (and set the difficulty harder so that these upgrades are kind of necessary to complete the game). (But, it kind of feels purer, in a way, without that.)
