I am not sure I would call them all indie games!
Yeah, a certain blue and orange game is definitely indie... /s
Also, cannot really speak for any of the games on this list besides Baba Is You, Portal 2, and and Isles Of Sea & Sky.
Not much to say about Portal 2 that hasn't been said over the past decade plus.
Baba Is You is a game I 100% recommend. Fun mechanics and I've also seen some amazing modded level packs as well. CBA!
Pretty sure my IoSS save might have been backed up onto one of my external HDD, but overall a good sokoban style game that manages to not be plain old boring sokoban. Definitely wanna eventually get back into it, unless my save is gone. Don't feel like starting over.
I also have experience with TTP1 (been playing it on and off). No clue about the sequel or the reawakened bull, but the original has so far been well worth it and fun.
