If you like Treasure Adventure Game (also on GOG) then you'll like Treasure Adventure World. It's more polished, adds things like mouse support and control rebinding without needing to run a separate configuration application. The graphics have completely remade, the soundtrack has been redone, though there's still an option for the original soundtrack. The game itself is very much like the original TAG, but with some restructured content and a bunch of new stuff. The dev seems to be hard at work on patching the game, with already several issues fixed as you can see on the forums. For the actual game, it's a platformer with a bunch of that metroidvania but with some collectathon elements. However there are some awkward portions where something is just out of reach but it looks like it should be reachable. It's a bit like Spelunky in some ways, with the free original using pixel art and the remake coming out that used HD cartoon graphics, but they're two very different gameplay styles. TAW rewards a lot more careful observation and looking for hidden areas as opposed to Spelunky's opimisation of routes and everything being a trade-off. It has a massive world that you can explore somewhat as you like, with barriers that require new items to pass. There's a lot of side quests as well as the main quest. If you're looking for a longer platformer with a variety of bosses and a lot of content, Treasure Adventure World has plenty of offer.
