It seems that there are not many like bitballoon, easy and fast.
Do you know any to upload and try my game ?.
What about https://itch.io/developers ?
Edit: i got curious about this issue and tested the FPS. So far basically one layout and worked with 55fps+ with no problems.
I have a bullet shot, couple sprites with sine behaviours (one has also bullet behaviour) and 1280x720 res. Also couple every X seconds and Every tick events.
Phone is just a LG X Power.
