Thanks for playing our game! I'm glad you liked the idea!
I think we may have fallen victim to the thought process "Oh, we know the controls and the story so we don't need a tutorial" (and also we were already cutting it close on time), but I agree. There are a few ideas that weren't explained as well as they maybe should have been, but oh well!
I'm looking forward to doing more work on this (whether it's the whole team or just me tinkering and trying to figure out how Unity works).
