Wow this is one of the deepest games I’ve played for a Jam of this length. Obviously a tonne of effort went into this one - fantastic work!
The upgrade/mutations system took a while to figure out but it opens up a very cool kinda roguelikey sort of play.
I might not have been engaging with the systems well enough but from a design perspective the game does lean away from skill with the tougher stages/bosses and more onto having the right upgrades.
