I adore the ultra-low res pixel art style, the animations are good, and I enjoy the sense of humor. The game felt a bit (or maybe a lot) too hard, I clicked out of the game a few times due to the mouse not locking to the screen, and I disliked that the dialogue box covers the most important part of the screen (the bottom where enemies are spawning).
I could see this being expanded into an rpg/"upgrade" game and released commercially.
