I was bored, and had nothing better to do, so I made this.
[edit] Now there's another BSP. This one's got cameras, to view the action from better perspectives.
[edit] I've slowed the water down, and made the piano better. I also made the surrounding room better.
[edit] I made the water trough shorter, so you can see the circuit get completed when the cameras are on, and I dressed up the map a bit more.
You might consider an optional camera to show different view points and mabye brightening a lil bit, but really good!
Those domino-like falling blocks needed a bit tuning though. Turned out a bit short too.
I'd give it a 3.5, meaning 4 in the current system. Good job.
Nice work on the update! The timing seemed very fluid and believable for pretty much everything, and the ending is a smash =P
Great fun, we should do this again some day
