First, I loved the game. I'm very impressed by it as an old fan of DOTT and Maniac Mansion and I hope you start a kickstarter or something to complete it. 

Just wanted to note I found a bug that crashed my game.

After I had managed to use the grandfather clock with Bernard (and solved the clock puzzle) I later played with Hoagie. I was really just going to enter the grandfather clock, but for curiosity I just wanted to see if what happened if I tried to make Hoagie use the grandfather clock afterwards. Bernard stepped in and said "I'll do it"... but since he had already done it Bernard would just stand there forever, basically in a freezed state, and I couldn't do anything anymore but quit the game. 

Luckily I didn't have to play through the game again because the autosave just put me back to Hoagie before I had clicked on the clock.
