Hi! 

My game name is Room. 

It's a desktop puzzle game where you need to use the clues from the computer to escape the room. You got only one chance to do this. If u fail solving the puzzle the first and only time... The application won't open again.

Hi! Thanks for making this post, I feel like posts like this are the reason people played my game at all haha. I played One Rhino and left a comment on the page, great work!

If you get a chance, feel free to try my game, AAA_GROOVE: https://itch.io/jam/gmtk-2019/rate/462268

It's a one-button rhythm side-scroller. Everything in the game is synced to the music, including the hazards!

Here is ours. It is about dodging (or smashing) pigeons with damaged plane

I'd love it if you played my game,  Grapple. It's a Gameboy-style Metroidvania, but with only one upgrade: a grappling hook!

If you do play it, please play the bug-fixed version, linked on Google Drive at the bottom of the game page. It fixes some annoying crashes.

Hello! :)

In our game you can eat a ton of guilt free cupcakes while solving puzzle platformer levels featuring blobby bois!

We'd be happy if you could check our entry as well. It's a top-down shooter where you only get one bullet you have to pick back up.

Hello, 

Would be great if you find few minutes to play my game:

https://itch.io/jam/gmtk-2019/rate/460800

Fast Paced 2D Top Down Shooter :p  https://itch.io/jam/gmtk-2019/rate/461364.

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.
Its a bit hard to understand first time but you can give it a shot.
   

Hello there, it would be awesome to have you rating mine:

https://itch.io/jam/gmtk-2019/rate/460901
