One of the best games this jam! Visual and audio are good. Love the concept of upgrading and breaking your character at the same time (my game also uses the same concept :D)
That said, for now the best upgrades are attack speed and damage are enough to survive forever, I only need to pick these upgrades and erase all the bug after that. In my opinion, because of the lack of surviving goals, enemies's variety ... make it feels insignificant to have to constantly upgrade my stats.
I'm willing to provide even more and detailed feedbacks if you guys need them! Overall, I had a great time! This game has so much potential and rooms to grow into a hit!
