The engine looks solid and I like the diversity in the worlds and this whole randomness, but there were problems on the way. Like, major problems. I picked up the artifact on the seventh floor and everything just kind of died before me until the end of the game. I mean, everything did 0 dmg to me because of my ridiculous defense stat and I just could walk through everything right until the game's ending. And this was also my first run, so I haven't experienced the game much, because I had to be careful only in the mystic caves and then the game just kinda played and finished itself. The fact that there were medkits on my every step healing me fully in the last worlds didn't exactly add to the challenge, too. Also, there was no boss in the digital world.
