Appreciate the honest feedback! The intent was so that you could choose to manage your upgrades to stay balanced and be ‘safer’, or you could go all in on a build and risk the game getting a lot harder (much faster enemies, firing rates, etc). Could definitely be tweaked.
Skeletons should have some randomized delay between each other, cause I noticed that too when developing, but good to know it isn’t super consistent. Enemy AI is definitely barebones, but it was good enough for a jam I felt. Something to work on for sure.
I do wish I focused more on enemy variety, maybe adding bosses to break up the rounds. That and adding more risk/reward options. Lesson learned.
Still, I’m glad you enjoyed it despite its flaws ❤️
