Hard agree on №3! Building all of the mechanics took me most of the time (well, setting up the animations also, I'm still getting used to Godot's animation player node, made my friends do that for me in prior projects XD), but after that it really picked up the pace and I just had to add in the assets as Der was finishing them.
Thank you for the reply and for checking out our game! I'll go take a read on your post ♡
Also wow! Congrats on the first solo project! In my eyes it takes superheroes to be able to finish everything alone in such a short amount of time. x)
