IanSkelskey!!! Welcome back!
I'm not one to delegate out work, but.... There's plenty to do
Pretty much whatever you're interested in. Secret grottos, old woman's potion shop, hyrule shooting gallery / bombchu bowling alley, or my personal favorite: game effects! Ya know, stuff like fire (which was recently re-done but my personal opinion is that it could be much better), damage explosions, bomb explosions, blocking sparks, splashing water, ect ect.
Honestly, there has been nearly *zero* work done on in-game effects. Whether they're pseudo-animation effects (such as fire) or true animation effects (such as damage explosions).
But hey, who am I? Death--Droid may have a better idea of what you'd like to work on, but ultimately the choice is yours. Good to see you back!
