Very fun gameplay; pace is pretty amazing yet challenging. I really like this style of upgrade-to-win, I've seen in other jam game loops - so naturally engaging, but scales really well here.
Obviously the art is phenomenal - actually gives me nostalgia with the skyline, maybe I'm crazy, but It kinda reminds me of Rampage.
There is like one way i found to KINDA cheese the game (you did a good job of anti cheese btw). Missiles dont spawn on the top layer.
wow Congrats on your release!
