Nice game. I think the damage/armor/heal/money system works quite well and is really intuitive. Furthermore, the core gameplay loop is fun and definitely has the potential to become addictive. I also like how the protagonist kinda looks like Uma Thurman in Pulp Fiction.
Embracing RNG is most likely the right approach for this game, but I didn't like how easy it's to get screwed at the beginning, especially for the copycat enemies which are frankly kind of boring to fight at the start before you get any items. I think I played 8-9 runs and at least 5 of them ended against the first enemy, otherwise it's quite easy to snowball so balance is a bit off.
This is just my opinion but I like it when roguelikes give you a free item per level because that makes each run different from the get go and would help even out the power level at the beginning. I think the final boss is fine although the permanent greed makes any yellow item worse as a consequence.
I also noticed the tourist guys with sunglasses give you permanent useless symbols and I'm not sure if that's intended because it's by far the harshest penalty in the game which is weird coming from an otherwise easy enemy. Another bug I found was that the curtains from the rewards screen stay on forever if you press F5 to reload the game.
