Very fun & addicting game, gun crafting system is both simple and deep and allows for creation of some busted builds. There were some quirks here and there (like Pi & Fra saying "reduced by X" which gives the impression of a flat reduction rather than division), but testing allows to iron out quirks and test different combinations of items.
Some suggestions/stuff that would be cool to implement:
1. Add autofire pls my fingers hurt from holding down left click
2. Make it clear that status effects DON'T STACK. I was really confused as to why my gatling burn pellets started sucking hard come level 15 until I realised that reapplying burn does literally nothing for you except reset the duration (hence why my 6 dps burn was taking a while to kill 200+ hp enemies).
3. Add more stats to the stat breakdowns of each gun (stuff like bullet radius, bullet speed, etc) as well as individual stat breakdowns for any submunitions created by modifiers like Tra or Fra.
4. Add more graphic customization options (turning down explosion/spark graphics, decreasing player bullet visibility, etc.). Turning off bloom barely helps at all when I have tons of exploding homing rockets that obscure literally everything, and also kind of makes the game look dull and sad.
5. Add different gun types (maybe unlockable/choosable at start of run). Maybe a bulky gun with higher modifier cap but reduced firerate & bullet speed, or a laser gun with drastically shorter base bullet lifespan but fires a continuous stream of energy pellets instead of 1 big bullet.
