I've already replied to the concerns about the weapons in previous comments but a few things of note:
- Envy's shots have always been the same fire rate as the base weapon and the same speed
- Greed's main feature is the charge shot that instantly kills ordinary enemies and pierces 3 targets.
- I'm working on reworking the enemy AI as I write this out, rest assured there will be many more enemy types.
- All the weapons should be fairly balanced in the actual dungeons because of variety and less swarming, but it will take some time.
- I'll add more weight levels at some point. It's just that the animations take quite some time to make (Hopefully that shows in-game, I tried my best to make the animations nice with a sense of weight and size)
- Stay tuned, there's a lot more to come and even some concept art for bosses over on patreon.
