The art style is very unique and the music is great too. I spent more than ten minutes just jumping around and didn't get bored at all.
I ran into an issue where I couldn't seem to damage the Boss Robot. I had to watch your video to realize that activating Wind Slash is what turns your normal attacks into ranged attacks. This seems like it might have been a technical problem on my end.
Good game! I look forward to seeing more map designs in the future!
