Thank you for your comment! I think we bit off a lot more than we could chew, and in an ideal world I would have made a tutorial level. C'est la vie! It's something we can work on for the next game jam!
The resource you collect is coins, although I certainly could have done a better job at making the coins *look* like coins, haha!
The third room was my fault, and did not set up the camera bounds for the room correctly. The camera should extend up a few more tiles, but we'll get that fixed for next time!
We both definitely think that grappling and momentum were the best bits of the game, and is what we were focussing on most of the week, I'm glad you enjoyed that aspect!
