I decided to try Treasure Adventure Game after it suddenly showed up for free in my GOG.com account. But don’t worry if you don’t have a GOG account — you can grab it for free directly from the creator as well.
Billed as a retro-styled exploration-based platformer in the vein of classics like Super Metroid, Treasure Adventure Game certainly contains a lot of old-school design elements that might put off some players. There’s a lot of backtracking… seriously, a lot of it. There is a system for fast-travel but it’s not introduced until late in the game and is not very obvious; I didn’t even find out about it until after I finished the whole thing. There are many jumping puzzles where the player can fall and lose significant progress, leading to frustration after missing the last jump in a long sequence. Saving is only possible at special save points, meaning more lost progress after dying. But despite all of this I found I was enjoying myself immensely.
