I started to play, but did not finish it yet.

The first impression was good, I like how strategically the enemies were placed, very difficult in some places.

I was also surprised there was a little story in the readme, and I also noticed some puzzle elements.

The eyecandy is not so good. It looks alright, but more could be done with the tileset.

No tilebugs, apart from some with lava tiles.

I hope that's enough to get you satisfied for now, I can't say more about it as I did not finish yet.
