This is a fun idea! I got abit annoyed that the camera didn't pan down, when I went to the ground. I also think you die abit to easily from dropping down from your own raptors (on purpose). It's a bit hard to tell what the limit for how far I can drop is.
Overall, I got into the stacking

got to the red bird thing and couldnt beat it or get passed it. stacking the things were pretty fun.

It does not work for me:

The following features required to run Godot projects on the Web are missing:
Cross Origin Isolation - Check web server configuration (send correct headers)
SharedArrayBuffer - Check web server configuration (send correct headers)

I wasn't sure how to get passed the red wall, which is unfortunate because I wanted to play more.

Other than that, mechanically this is super fun. Stacking the unlimited raptors, making raptor ladders, it was satisfying. The controls were tight and I always ended up where I wanted. Initially I thought the death box at the bottom needed to be a bit more forgiving, but once I got the hang of the raptors I appreciated the jeopardy and having to slow down and be careful when crossing large gaps near the top of that first section.

@rolferm sorry about this - the html version doesn't work on ludum dare, but it does work on itch.io as linked. My bad, I uploaded everything in a bit of a rush.

@magnusfurcifer thank you! Sorry about the red wall thing, it goes away when you jump on all the enemies - I was supposed to put tutorial text about it but forgot to do it. Very sorry!

Interesting take on a vertical platformer. Reminded me of "Rainbow Islands" which isn't a bad thing, we need more games like that :smile: If you haven't played it I'd definitely recommend checking it out to figure out what to improve in your game.
