Thanks for playing! I would say making a 3d game in Godot is much harder than 2d, but by no fault of Godot...3d games just require a lot more effort and disciplines to get to a similar level of polish than 2d.
Tavoe was the workhorse on the less glamorous systems. Coming into the project he had the most experience on Godot, Blender, and general game development. I cannot understate how much time he put into making things work so we ended up with the game we have now.
As for the puzzle levels and character actions... You can blame me for those. I thought of each jump as a little puzzle that needed to be solved to complete. Being the person who made the glide and dash, and a fan of precision platformers, I found my traps to be of medium difficulty. However I know better now.
If you're interested I could tell you of some of the tech problems we ran into for 3d, though tavoe would be able to give the most detail.
