I did not see another one like mine, so i think i can post here. 

Game is a platformer, where the every power-up is deadly overpowered. They are like this, because game uses only the number 1, and no other number, so it just puts 1's side by side, which makes you speed up from 1 to 11, then 111.  Same for your jump and your score too. So you need to reach the exit for every level with using power-ups, but taking more than you need for extra score can make you more uncontrollable than you need.

Solve little puzzles and beat 11 challenging levels!

I wouldn't say the base concept of the game is original, but the way I expanded upon it is original

My game is called One Shot In The Chamber, a wave based survival game where you must fight off hordes of enemies with the catch being, you have only one bullet. Fortunately, the bullet is magic and you can summon it back to you or teleport to it. Using this unique ability, you must survive as long as possible in the chamber. Here is a screenshot of the game and the link to the game page: https://mark-auman.itch.io/one-shot-in-the-chamber

Here is my game a Horror Theme game where you need to control a Robot with Text Commands to get you a cure - https://itch.io/jam/gmtk-2019/rate/462295

Proof, that my mechanics are unique: Nobody understood them :D. But you can try to if you want to ;)
OneBlock is a platformer with only one platform. You can set the teleporters to teleport the platform around the place, making it a tricky puzzle-platformer game.

   

I've never seen a rogue-like where you have only one inventory slot, so I think in this regard my game is pretty unique :D Check it out: https://itch.io/jam/gmtk-2019/rate/460262

We think ours is a little bit different: https://itch.io/jam/gmtk-2019/rate/461722

The objective is to get the camera and take a photo (by holding LMB) before the celebrity leaves.

2D puzzle platformer with gravity switches, except you can press every button only once per level. And it’s kinda hard..
