Hey,
cool game. I like how polished it is with a nice amount of content for three days work. Level Ups, Power Ups, Combat, Cats, Treasure Chests. Nice. Movement is smooth and esp the sounds are quite nice, as you got feedback on everything happening. The idea for the style is really cool, but I do not like the execution with the flickering very much. I think I would have liked a higher rendering resolution more, so that it looks lowres but doesnt have the pixel jumps. Normally the current style works also ok, but with the monochromatic green, its to wild for me. :D
