Love the environments and the mechanics. Find the final boss on each pyramid to be very difficult to defeat. And if you fail, it takes a long time to get back to try again. It may not be rogue-like, but think that you should get repeated attempts at the end boss if you've reached it.
Have bought an alarming (200+) games from GOG since I enjoy reliving older titles. This one is the first that just seems broken right out of the box (so to speak). Can't save settings, keyboard only use does not work properly at all, can't seem to save games, exit game, etc etc. Big disappointment
