Thanks! We were aiming exactly for that vibe, so I'm really glad you got it!
The mouse thing happens in web build, and I saw it happen in other unity games. Guess it's a unity web player thing :/
I had one tester report some hit detection issues. It did the best to fix them, but in the end they didn't occur at any machines I had access in my house.
All in all- really glad you liked our game! If you liked it, you may be interested in other stuff on my profile :)
