Game looks polished. If you add a story, some variations, levels, basically, you already can call it complete. Jump on W and shoot on Space was very confusing at first, I would reserve Space for jumping like in the majority of games with jumping characters. I don't even know what key will be better for the regular shoot, maybe Ctrl. Interacting with a fountain on E or F, the special attacks on Q or numbered keys. At least I assume that will appeal to a wider audience
