I liked the idea of the different mechanics and think it could all work together but it doesn’t quite land. I enjoyed the upgrade mechanic though getting nerfed movespeed twice in a row was a bit of a downer. Game seems incredibly easy so I never felt any reason to actually lower my health for damage. I also have to admit I found the firing sound really grating and that dampened my enthusiasm. Still it all functions and works and the ideas are solid. Good job! :)
