When dying, it would be nice to be able to view the dying scene, and observe characteristics of the surrounding monsters: pointing at monsters with the mouse does not reveal their characteristics once dead.
Sorry, there's a bug in level "rowing" (upper right in second page of "hard" levels) : column 17, "2 3 2 1 1" should be "3 2 1 1". This prevents the level from completing.
Ths controls don't work for me. the games doesn't notice when I lift keys, so the character is always running in a direction until I hit the direction key a second time. Hated that.
