Seems to me that there is a need for a mobile friendly filter on submissions tab.  I will play and rate honestly all the games of this jam whose creators took the time to make them work on mobile.

Of course I also made my submission playable from mobile, feel free to try it out.

The mobile functionality is a little off and I ram out of time to fine tune it, but I added controls, you can enable them in the extras menu.
Here is the game.

This is mine, touch controls can be toggle in the main menu before starting, also found some ohtes that use is, like Yellow eyes which is an awesome game too!
