The game was great! It's a WarioWare style collection of minigames, and I really like this genre, the graphics are cool and add a lot to the game's atmosphere.
The only issue I have is with the minigames themselves. I'm just bad at video games, so I couldn't beat any of them. I only made it to floor 5 because of the Janitor. I bought everything he had except the instant death item on next challenge, and I ended up with 6 extra seconds plus all the upgrades, haha.
Overall, it's a great game, I'm just bad at it!
