Hello Yourking77 !
- Portal is a legacy tile, located in the RPG asset tileset dungeon crawler pack (Super Retro World by Gif) by Gif (itch.io) (in legacy/legacy_tiles.zip)
- Waves are arranged here in the current atlas :
They are not animated tho, do you want an animated one ? The RPG asset tileset overworld pack (Super Retro World by Gif) by Gif (itch.io) got some animated beach water tiles (not exactly the same). If you want I can send you the tiles directly so you don't have to pay the whole pack for it.
