Got a question that bothers me, hyper casual graphic is simplified, if i draw something realistic but in space theme will i be disqualified?
No not at all, there will be extra points given to those who follow the game theme closely, but you will not be disqualified for using realistic artwork. I think you could potentially still make that work with a hyper casual art style as well.
Oh one more question! Can we submit more than one game?
No, we are asking that you submit only your best game
So making it "Hyper Casual art with a twist" is ok!
yes! and Hyper Casual does not have a super narrow art style. You can look at the top games released by Ketchapp and Voodoo as a reference
