Looks clean, plays clean. Was pretty fun even if I didn't get -that- far (this is a good sign!). Only thing I'll say is, I was confused about the left-click at the start of the game. I didn't understand that I didn't have an ability yet (the meter still showed and made a sound, which confused me).
Is the minimap supposed to say "str_you" over where I'm located? Or is that a string that wasn't translated?
I love how the skeletons go ham when you hop on them, it's just funny to see.
Honestly this feels like a demo to a pretty good game! If this ever had a follow up, I'd love more variation in the visuals of the world itself (like the level tiles), as well as the music.
