I really enjoyed this game (once I managed to get the sensitivity right ;) ).
I hardly know where to start since there is so much good stuff going on in this!
I really like that you went with a mono-modal system. It was a smart choice especially since a bow is usually more tricky to get the hang of. Though hilariously it did remove some upgrades a few times by mistake because of a mixture of split arrows and ricochets.
I like that you went with the bow instead of the default of using a gun. The pullback, reload and having to lob your shots add some good tension. I like the use of stamina draining while you draw and I like the idea of the trade-off of sprinting vs firing but I think the balance was a bit off because I found it quite frustrating at times. Another minor gripe is that the
I like that the gold disappears which creates a push forward momentum to the game instead of hiding and being overly cautious.
The arenas were cool, and I liked the variety you gave with the different biomes. One thing I did notice is that the entrance "door" allows you to cheese the enemies by poking out, shooting, and then hiding. I think the door should just disappear and throw you into the thick of it haha.
I know the shop, upgrades, classes system come from autobattlers but it feels like that set of mechanics should have its own name. I've been quite into those games lately and was wondering which inspired you to add them in? You managed to get a really good breadth of abilities and synergies which is super cool! I imagine it's a tough thing to balance but the randomness definitely helps in that regard.
Honestly, the only the main issue I had was with balance, the shop upgrades needing to get a bit more expensive over time, the enemies getting a bit stronger (and maybe have a bit of archetype variety) but I can imagine that that was more down to lack of time than anything else. I hope you work on this some more. I'd love to see where you go with it :)
Overall I can't believe how much you got done just by yourself. Big props to you!
