I've been running through games on Epic I grabbed, but never got around to trying, because I got stuck at a puzzle in Train Valley 2 where I'm not even sure how to get a track from a building to any area accessible by anything else without having to resort to a guide *again*. I enjoyed the game up until all of the puzzles became "you'll never guess how to connect this building to anything so you can start trying to do the logistics stuff the game is based around, because we intentionally made it difficult to read the terrain. Fuck you." Puzzle games (and some others from all genres) love making the "what am I supposed to do? what are the rules? a puzzle that you need to solve before you can solve the actual puzzle, because it's easier than making something clever. Or they're just bad at communicating.
The Forest Quartet: puzzle game. Pretty. I got stuck at a puzzle where I have 6 poles that I can rotate, which spins 3 different levels of balls. Sometimes that balls line up facing a direction if you spin them long enough (usually several minutes). I'm probably supposed to line them all up in a particular way, but don't know what way, have no way of knowing if I got one or more correct, and got tired of waiting for even a single one to get lined up nicely. Including the 10 minutes trying to figure out this puzzle, I'm around 15 minutes into the game, and don't feel anything keeping me interested.
Out of line: platformer with some puzzles. Figured out the things on the ground that I can jam the spear into are supposed to be levers when the spear is in there, and control platforms. Now I'm on one with a partner who can hit a button for me if I do the right thing while using the lever. I've also trial-and-errored myself into know which spots are for them only and which ones are for me only. One spot I can put their platform spins 2 spiked platforms. They are perpendicular to one another, so I can't get them both at a usable angle, and one side is covered in spikes so the best angle also kills me. I can maybe figure out something so I get stuck on the next puzzle instead, but not being able to tell where I could and could not go without dying repeatedly already frustrated me enough that I need a break.
Black Books: it looks like a deck-builder so far, with choices affecting how you progress through the game. Looks like I'm going to damn my own soul to save my beloved from hell. Metal.
