agreed, simply more upgrades would be nice.
Also I dont know if the carb monster give more exp.
But I feel that they should since they take 2-3 hits to defeat while the normal guys die in one hit
Thanks for the feedback! I was able to release a new version of the game today following the jam. It should address most of these issues, including the level 10 and 11 locks, no more enemies spawn when a boss is present, and a rapid fire upgrade for more variety and to make things more manageable. If you have any more feedback would love to hear it!
