Well I managed to reach the top in 4:17!
This was really neat, the premise funny and original, and the platforming mostly felt good but with a few issues I noticed that I found frustrating.
For starters, the cursor isn't locked to the game window. This is an especially annoying issue for me because I accidentally clicked outside of the window a couple times and then got blasted off the platforms. And frankly it's just distracting having the cursor going back and forth across the screen.
Also it seems like the drop shadow doesn't always follow the player, which made jumping on the thinner platforms more difficult as I couldn't easily tell if I was going to land on them. I don't know how you have your setup but when I had a shadow for platforming in one of my games I just used a projector attached to the bottom of the player. That way it always follows the player, and you don't have a full shadow floating in mid-air. Just a suggestion as something to experiment with post-jam.
Besides that though, it was really cool seeing all the different platforming mechancis you managed to implement! Double-jumping, grinding on the straws, ledge-grabbing, wall-jumping, sliding, and bouncy platforms. That is quite the list!
I also loved the background detail of being able to see out the window, and having one of those old car city rugs on the floor.
Overall was a great little platformer, good work!
