Ahh, thank you for the clarification about the mouse thing
I played through again and I was able to solve the puzzle thanks to the update (intriguing ending). I only hope the solution's not too obvious now though; I'm not sure if I looked hard enough originally because I guess for some reason I expected the solution to just pop up in front of me or something
Best of luck on your future projects from one gamedev to another, I'll definitely check them out if I can
