I had a lot of fun. It ended up taking me two tries to beat the game. Getting a random weapon for each room--even boss rooms--is a fun mechanic (though I imagine decently tricky to balance, which I'd say you did well). The enemies themselves, although not many, each felt unique, which is good, but their ai may need a little polish, because they end up getting stuck behind walls a lot. The music choice was great--really set the tone.
What I really missed, however, was clarity. I had no idea how close I was to death, how long my random weapon's cooldown was, or how far I was in a boss fight. It took me until my second attempt to realize health is persistent between rooms.
All in all, good game.
