Quite a nice game (I especially love the graphics) but I wish the gameplay relied a bit less on luck. Unless I'm missing something, it seems sometimes there is no way to guess you're going into a dead end until it's too late. I tried going with caution and going all-in with random jumps and both strategies gave the same results, only with the former being slower. ^^
Still a very fun random-choice game with an impressive level generation algorithm given the time limit! I don't know what you could add. Maybe some narrative with a story uncovering as you go deeper in these mines?
