An interesting experience; I fell into the trap of repeating the game over and over until I found the "true" ending almost by pure luck. Even still, I'm not sure if I've found everything this game has to offer, such as the what the diamond shaped icon in the save slots represents and
I liked the mechanics of the game the first time, but of course they became monotonous as the replays continued. The secret of this game was rather clever and well hidden, almost too well hidden. The simple style combined with drawn art scenes set the scene rather well and the music was fitting enough.
I only encountered one glitch, if you walk back into the hallway with the statues before the boss door on the left or right, you can get stuck on a statue causing the game to freeze/crash. Luckily the game auto-saved after defeating the third boss.
The story's conclusion for such an intricate setup was rather anti-climactic, but did well to explain the bizarre gameplay.
All in all, it was enjoyable the first time through, but the effort required to achieve any sort of legitimate ending was quite steep compared to the tame result.
