I did a 2-player run of this with my cousin and I had an amazing time. Everything was smooth and fun, we were very impressed by this game!
I wish there was a mini map to help know where we've been as we were lost a few times (but not for a long time and it wasn't frustrating. It's simply for helping backtracking since a lot of the environments look alike). It took close to an hour to beat it the first time !
I would gladly pay for a DX version on Steam/Itch with more levels, more enemies and bosses, more map designs and a randomize map mode :)
I'm a big fan of your games! Quest of Graal was insanly fun too, keep it up!
