Hm, so in the first level with the fossilized dragons, I went up, left, found a lever, interacted with R and it sent me back to the first “hub” location where you have to jump in the void.
I couldn’t find the first boss. I’ll refrain from voting as it wouldn’t be representative of what you made.
Otherwise, it was nice to have an intro but it was a bit long (a lot of lore exposition) and the text auto-advanced with no way to pause it and advance at your pacing. The default auto-advance speed was too high and I couldn’t finish reading most of the lines.
