Thanks a lot for the review and for playing our game. We are glad you liked it!
Yes the scientist can block you in few situations and glasses get sometimes stuck into a wall, we are aware of those bugs. Although the glass being stack in a wall might be a situation, where the glass lost you out of its sight and is waiting for few seconds (5) if it sees you again before returning to its original position. Thank you for feedback.
Looking forward to playing your game!
