This is a bit too early for th hub. One of the hub rules is to avoid sharing too early. Work in progress games are ok to show if they are demonstrating something unique, like graphics, game play or something along those lines.

This is just a red block with joystick controlled and jump with button.

One thing I like to think is a good indicator of whether or not you should share to the hub or not is the use of joystick controlled and jump with button. If your entire game consists of these 2 behaviours, and there is nothing else adding to the gameplay that means it's most likely too early to share.

At this point there isn't enough for anyone to really give feedback on, or give any constructive criticism.

What's the point? What are you trying to do with this. What is the game mechanic? Also, the character needs to move faster.
