Hey, thanks for the effort!
I was able to test it and really liked it. I was a heavy player of magic survival at its time, and this remembers me of it.
I like the minimalism of only having one thing to upgrade, it works well.
I stopped at lvl 17/layer 8 because I barely had any enemies at the screen, I think the power of the character escalated faster than the game difficulty.
I loved that everithing is code-generated. Who needs assets :D
