Great style, good visuals and music. Concept is clear, it all makes sense. It seemed like option 1 had the best stats, I just kept using that. Occasionally used option 4 if I was overwhelmed with lots of enemies. The spreading of your base slime stuff mainly happend in the front and the sides, I would've liked some to spread at the back as well, it left me feeling exposed at the top of the map. I could see this being expanded into a bigger game, with more enemies, more options, etc.
