Ok so I've only played a couple in the OP so far, but it's a start:
The Sun and Moon
He already knows what I think about his games - but Daniel Linssen is a genius. Javel-ein and Roguelight are two of the standouts for me, but The Sun and Moon is, mechanically, the purest of his games. It's a "physics" platformer in that an understanding of momentum and angles is key.
Fiendishly difficult but never unfair - highly recommended. There's also a free version to play.
This War of Mine
Hmmm. This is a game I'm still not 100% on about how I feel. Aesthetically I like it; the pencil lines are nice, the graphics are effective and the music and sounds are really well done. Gameplay wise it never... grabbed me the same way it did some others. I often find in this kind of "management" game, for want of a better expression, that things quickly get out of hand - but this is exacerbated in This War of Mine, entirely deliberately.
Build the wrong thing early on and you're looking at a restart, but over time food can become scarce, again deliberately, and you begin managing food, moods and anything else the game throws at you. It's an extremely interesting game, and I like that it doesn't try and force some kind of overbearing message onto the player; this is simply a game about the people left behind. I'm just not sure how fun it is, and that's ok.
Highly Recommended
The Sun and Moon
This War of Mine (just)
I dont mind restarts in general, but restarts are extremely repetetive in this game, since you need to run through the exact same missions all over again.
