Great work on the game, it's very fun to play and it has a lot of potential if you add more weapons, abilities, bosses and such. But I found the game very dark, people with bad eyes could have a problem playing your game, maybe making it a bit brighter or putting a light aura around the player would help a lot. The stab move would sometimes pull enemies in my direction, if this wasn't intented it's definetly something you should check. Also the sword attacks activates the ladder, maybe it was an oversight? I can already see people using it as a speedrun strat. Also regarding the ladder, it would be nice to make it so that the coins you dropped would be collected once you use the ladder, because the ladder would often spawn beneath my character once the floor was completed and all my hard earned coins would be lost in the transition.
Very nice job on the game, I definetly would like to see a full release!
