Nvm not on my wishlist. :)

Not on wishlist, but I 100%ed every Hexcells game out there (played 90 hours of Infinite untilI became bored with it), so definitely interested:

I have it wishlisted, and love puzzle games. I have many hours in The Witness and Talos Principle which I can't recommend enough. I was near the end in The Witness, but 'The Challenge' got me frustrated and I stopped playing. Time restriction in a puzzle game is NOT a good design choice Mr. Blow.
No complaints on Talos, completed a game and collected all the stars. Didn't like the story that much but puzzles were extraordinary, especially for some of the stars. DLC for it, Road to Gehenna, is one of the rare examples today which isn't just a cash grab. You get a LOT of content and getting stars in it is considerably bigger challenge than those in the main game in my opinion. Couldn't get them all, but I'm planning to revisit the game again.
From 'smaller' games I completed all Hexcells, Divide by Sheep and Hitman GO, all highly recommended. Highly in my wishlist is Stephen's Sausage Roll, which got a lot of praise from Jonathan Blow and apparently is harder than The Witness. 99% positive rating on Steam also doesn't hurt. :)

I LOVE DROD!!! Pleeeeeeeease! I've got loads of time in loads of puzzle games, because I play them more than pretty much anything else. On GOG DRM free versions I've probably played about 100 hours in DROD 1 + 2, but I don't have Gunthro! It's wishlisted, naturally :)

Never heard of this game. Will check it out.

EDIT: Huh. Reminds me of a really old, really basic DOS game that I played when I was a kid. I can't remember the name though.
