Very fun and enjoyable game, with an awesome gameplay loop! There's already a pretty good diversity of weapons and characters which I really liked!
I found the gameplay very fun, with a pretty good mix of strateging and avoiding enemies. I loved experimenting with each of the characters and getting more and more powerful as the game goes while adapting to the luck.
Compared to other game's of the genre it's very active and needs a lot more of my attention, which I really find enjoyable as these types of games can get pretty boring and dull fast without needing too much player input but I never encountered a moment like this.
I don't have many complaints, though I think a way to see the information and stats of my current weapons could be something really useful for deciding what weapons to sell and what not.
But overall I really liked the game, the fusing mechanic is pretty interisting and fun to play around seeing the different fusions, overall, great job!
