It's alright. First you explore and gamble, then you just gamble. I would suggest get rid of stamina bar - it annoying on platformer level and just kills you once on the final. Room with many doors looks fun first but then when you need to check all of them and they are the same it isn't that great. Would be nice to have something more exiting in the end since it took quit a few attempts to achieve it but I understand that time is limited.
