Two possible options at the moment, but both based around persistant upgrades as you progress through levels.
We're looking into a loot based system where weapons are built and upgraded using lots of different parts found (maybe randomly) throughout the game.
The other way is just to have a weapon shop with unlocks and upgrades bought with crystals collected throughout levels.
temporary super powerups are also kind of a common genre staple so there might be some way to mix that in too.
