Recommendation engine: Downvote any game you've heard of before
This might be a slightly unusual attempt at a prompt, but might draw some appealing unusual options.
The way it goes: Suggest games, ideally the kind that you believe would have relatively broad appeal. Don't feel bad about downvotes, but do downvote any game that's suggested if you have heard of it before (Perhaps, give some special treatment if it was literally your game of the year). This rule is meant to encourage people to post the indie darlings that took some unusual attention and discovery to be aware of and appreciate.
If possible, link to the Steam pages for the games in question, so that anyone interested can quickly take a look at screenshots and reviews. And, as a general tip, anything with over 1000 steam reviews probably doesn't belong here. While I'd recommend that you only suggest one game per post, at the very most limit it to three.
If I am incorrect about downvotes being inconsequential account-wide, say so and it might be possible to work out a different system.

Puzzle platformer/block pushing hybrid
The 2d platforming world and top-down world have smashed together. You control one hero from each dimension, who share the same space in the levels. You switch between platformer and top-down modes and must get both characters to the goal. The boss levels are hard but very cool, combining action and puzzles.
Also features local 2-player co-op and a generous assist mode.
That looks really cool!
It's fun. Way too hard sometimes but I think that might have been the point.
Down voting it but it's a good recommendation for those that like puzzle platformers like Super meat boy or the best parts of hollow knight.
