I am currently playing this game. I have found it extremely difficult. The Xal always seem to be accompanied by two Gash. I personally feel as though it would be better to have more saving/healing "tv(s)"in the caves. Or have less enemies. It feels like Pokemon games. Once you kill one, another hoard of them is coming after you to kill you. I've tried avoiding them in the first two caves (have gotten pretty good at it too) but once I hit a Xal it feels like game over. Also another little nuisance I found in this game is that if you die it goes back to the start page on New Game (and you can't skip the opening when you accidentally click it) which for a person like me who is used to it being selected on Load (in this case) it's a bit of a hassle having to go through the whole beginning again. Although with all of this information, it was really fun to try and play (eventually gave up because it was too hard even though wanted to keep playing it). The art is really interesting and unique. The back story above and name along with some of the graphics remind me of the game Omori which I am quite fond of.
P.S. To be honest I wouldn't mind being a game tester on the full version of this when it's been produced because it seems like it could have great potential if some of it's kinks were fixed.
