I found myself fueled by a deep desire to suck up an entire 6 pack of PBR and couldn't be satisfied until I succeeded

Other than the collision stuff you already know about, I think the only real issue I was having was the speed the power decreased once the bar got to around half way depleted. I tried it numerous times on web and using the exe and it did look to start depleting faster once it reached that point.
If it ever dipped below that for any reason, it feels bordering on impossible to get it back up and this was a huge problem if I got stuck between a chair and the wall and the nearest pile of small stuff to suck would have me close to half depleted once I went down a size. Once I got the groove going though and figured out the "right" routes to take, the gameplay was very fluid (got stuck on a tiny key once though?!?!? crazy and very realistic tbh)
This also happened once when I was zipping through trying to see the full map and it would nooot return to me XD
Overall a very good job though, especially for picking up Godot for the first time! I know it's got a few peculiarities other engines don't. The art is charming and I can see the work that went into it.
