Ah so sad, the game crashes when trying to shrink in the greenhouse x( I tried the browser version, maybe it's just this one. Or maybe it's just me x)
Edit: I'm trying the downloaded version, and it works :) I'll give you my feedback after playing it!
Edit2:
So I had a lot of issues moving. When jumping and wall jumping, it didn't always responded (which made the jump from books to plant pot very hard lol).
Also, I think the gun clipping into walls disturbed me. It made me feel I'm not where I am (don't know if it makes sense). You can render the gun with another camera and always place if in front of everyting. This way, the gun will always be in front of objects and the problem will be solved :)
Finally, once I was shrinked, I didn't understand where to go. At first, I leaved the cabin to see if there was insects outside in the garden. Then I came back and finally saw the wood plank to climb. Maybe some hints on where to go could fix this problem. Think like Mirror's Edge: everything is white except locations to go which are red. You could use the same approach in your game
Overall, it's fun. The theme is well used, congrats :)
