Lovely graphics, fun game! I included it in a compilation video series of all of the 1-Bit Clicker Jam games, if you'd like to take a look :)

Your graphics are really well done. I found the gameplay to be too slow in comparison to the speed of the music. There didn't seem to be enough time between waves to plan out purchasing upgrades making this a little bit more of an active experience vs an idle/clicker experience.
