I have a mixed review that leans mostly positive, but I think it's in your best interest that I explain it entirely :
I feel like I have a love/hate relationship with your game. The core loop is really fun I genuinely wanted to go deeper and pay off my debt. But once I entered the cave, I didn’t feel like I had any real choices to make. I just filled my inventory with two or three weapons of each type and came back only when I ran out of shields or weapons of a specific type. This way, I managed to pay off my debt without making any meaningful decisions and without getting hit even once.
Maybe the game would benefit from a payoff mechanic something like a risk-reward system or a "push your luck" dynamic. Right now, there's no real risk and no real reason to take risks. You can just return to the shop and re-enter the cave without losing any progression.
That being said, the atmosphere is fantastic! I love the art style and the sound design! (Though maybe the audio is a bit too subtle in some places like in the shop, where there's no sound when you sell items but overall, it’s very cool.)
I think you’ve got a really promising project here, and I just wanted to share this feedback to help you make it even better. Well done! :)
