I actually really enjoyed this game. Not too short, not too long. The enemies were fun, the map and its different areas were all cool to explore. The short tutorial level was also interesting, although understanding what the "?" (up-button) does took a while, but it was a game changer (I think it may be a little bugged though since sometimes it lead me further away when there were still gems/hearts to be found in the area I was in)!
