Id recommend the heartbeast platformer tutorial, it had so much in it that was super useful for 2D games in general, and is easy to iterate upon after

The new ghost of yotei is set in a similar part of japan and and time to princess mononoke so maybe it could be imagined as a gritty sequel of some sort

Ive always thought porco rosso or nausicaa would make for some really exciting open world games, especially proco rosso with the seaplanes and dogfighting

This looks really interesting and fun

Good metal
