This game is, as stated, in early development. The controls are a bit buggy/laggy. I had particular trouble dealing with ledges, and I had to restart the game several times because I got stuck in the water and it wouldn't let me jump out. If I accidentally clicked while I was swimming, I got the animation for a ground slam but didn't actually move at all. I was stuck in that animation and had to restart completely. The gauges for Korvald don't seem to react to any stat drops other than using rune energy for the special attack. Occasionally I got a glitch where the health meter would not disappear after defeating an enemy, and for new enemies it would just refill the bar without changing the title or picture. This usually went away by moving between rooms. 

That being said, this game has great potential. The story line is compelling, and the art is very well done. There are only a few sex scenes, and although it could use more it's clear that this is a game with sex, instead of about sex. Aside from the aforementioned problems, I didn't see any other bugs or clipping. If there was, it was hardly noticeable and definitely not game breaking. I look forward to seeing how this game develops.
