A fun little point-and-click adventure game. Decent graphics, animations, and voice acting.
The only negative I'd say is that it was very short and too easy. My first play through took about 20 minutes, most of that time was me going to get a pencil and paper to work out the math problem. The rest of the puzzles were very simple and obvious. Maybe this is targeted at younger gamers?
Since the puzzles do not change from one play to another, you can play through skipping the clues and just getting the quest items, once you know the answers to the puzzles. All you really need is the 3 triangles, the axe, and the key. And obviously to set the pipes right, but you can do that as you go. All said, you can finish this game in well under 2 minutes.
The only 2 issues I could find in the game were purely cosmetic:
1. Why does the one guy always walk backwards through doors? That's just odd.
2. If you don't hack the painting with the axe, it is hacked anyway during the game end sequence.
