My game is also pretty retro but more dynamic and challenging; https://hik.itch.io/polypuss
Here's Cosmic Climber - a jumping game with only one platform: https://itch.io/jam/gmtk-2019/rate/462343
This is a really cool game! It definitely deserves more than five ratings, haven't seen a game quite like this so far.

(also Mark has posted about a Discord server specifically for people with less than 20 ratings https://twitter.com/gamemakerstk/status/1159329962840788992?s=20)
Maybe the 400 mb filesize is too high barrier to entry for some people, I skipped it when I was at home but came back to it on my lunch break at work where I have faster internet. It's a really cool idea, so I hope more people see it during the weekend - I've heard a few people say they plan to spend the weekend rating games with the fewest ratings.
Hey! My partner and I finished our first game and I would really like for you to try it and tell us what you think!
"One Item: Yo-Yo". Use your yo-yo to push, pull and swing yourself out of this crypt in 3 levels focusing on three mechanics using "only one" item. https://itch.io/jam/gmtk-2019/rate/463664
Hi!
My game is called 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.

One of the screenshot from my game.
Our game is named Impulse. We have only 16 ratings. This tricky, single-level game will put your platforming abilities to the test.
What's waiting for you in the dark? Only One way to find out. Be Impulsive and take a leap of faith.
Good luck, and thank you for playing.
Only One Sprite was used to make Only One Level, and you get Only One Pulse to help you out. 
Really loved the OP's game and hope they continue to work on it.
I made a puzzle platformer where you and the goal are the only things in the level. I'd appreciate any and all feedback: https://h-labs.itch.io/only-you
Here's my game, 'You have One Shot' - an FPS that you have to line enemies up in rows in order to shoot through them to get a combo kill. Check it out here: https://ultraskull.itch.io/you-have-one-shot
Hey! My team and I overscoped for the jam, but I'm super proud of it and it would mean a lot if you were able to take the time to give it a play and rate the game!
MICROVANIA - A One Screen Mini-Metroidvania with a Twist! https://itch.io/jam/gmtk-2019/rate/462198
And a few notes to help you play it! (The Game Jam build has a few bugs and quality of life issues)
- It works with Keyboard OR Gamepad
- You can view the controls in the menu (Esc or Start)
- The Player has 3x Health but will be instantly killed by Dragon Fire
- If you die twice, you should close and reopen the game (it breaks more and more with each death)
- There are two Winning Endings (You Kill the Dragon, or You Give the Dragon What it's Looking for!)
- There are 5 secret Gems hidden throughout the game if you can't find the last one, keep looking!
Ok, so our game is Rogue One:
https://itch.io/jam/gmtk-2019/rate/461305
It's a roguelike where you only have one stat, and said stat is your attack, your health, speed, etc. You get blessings and curses hat also depend on that value, and some enemies stats do the same. There are 4 enemies, 1 boss, 3 weapons, shops, an elemental damage and resistance system with three elements and variants for all enemies, and the game is procedural and infinite. Try it and tell us if you like it, we're really proud of it and hope people see it and enjoy it ^^

Hi this is my game.

Use your memory and observe attentively your surrounding.

Hi! We attempted to build a mini-Metroidvania!
And we had to come up with some clever mechanics to reinforce everything being on a single screen! I'd love to hear your thoughts! <3

No the issue is that my laptop is really rubbish and can only play basic games. Luckily that's been fine for most of these, but yours has fancy graphics and stuff so it runs at something awful like 8 frames per second. Either Amy can check it out, or I can dust off my desktop to get it working. Nothing your end!

This is HiVeMiND, where the two blobs share one brain and have to reach the exit, on different platforms, using the same moves. It comes with 15 levels, aaand with a level editor so you can torture yourself and your friends :P
Check it out, if you have time. We'll make our best to play, rate, and comment on your game too.
