The Resolution is a bit weird. The game mechanic is rich in potential and well demonstrated. Slightly polishing the Difficulty curve and monster appearance rhythm within a level may let the game have a better experience.
Thanks a lot. The resolution is indeed messed up in the browser version. I have many more ideas and I will definitely polish the game more. Also could you elaborate a bit on this monster appearance rhythm part, I don't get it.
What I mean is that on top of these isolated waves, I would prefer a more flexible, more fluid enemy spawning mechanism. It may help the game more immersive and create a smoother balance between challenge and skill.
