Nice concept! The increase of power is really satisfying. And although the game has many stats, most of them provide a nice balance and feel great to obtain (the only that felt arbitrary to me were stamina, energy and luck).
However, the games get quickly easy, and progress is really slow. I though 1 wave meant 1 spin, but apparently not, and I wasn’t really sure when I would move forward, it just felt forever each time. The game quickly becomes trivial, because you don’t land on that much combat. So quickly I had powerful weapons, health and armor that would never decrease, and tens of thousands of gold. Although axing ennemies was fun, I felt I was just spending time grinding. I eventually lost on the second boss because, although it wasn’t difficult either, its health bar was ridiculously large and after what felt like 15 minutes of just spamming the attack button it decided to teleport on me and insta-killed me.
So yeah I think it needs some balancing. But there’s already a great work on variety (I really liked the weapons names). Also visually wise, there is not a lot of sprites, but I most applause the efforts on the pixel shader and the many, many visual effects that all feel very satisfying! Sometime making the screen hard to read, but imho that’s the fun of these kind of games: making a lot of visual mess to feel powerful. And your game definitely nails it!
