So, the concept is cool and I can see it developed further in a full game, I saw a roguelike card game with a similar mechanics one and it performed well on Steam !
But this entry is still a bit far from it,
You need to add more feedback for the players ( sound / effects / colors or whatever ) I could not see my healthbar, I thought the game crashed when I could not move or do anything first, before I understand I need to click on a door to go.
But I guess you did not have enough time to add everything you had in mind:)
Keep working on it, you have something interesting I think.
