This is a pretty simple game concept, like flappy bird or the games that flappy bird was based off of.
You should design a character to be the little dot you are moving. You should also add a meta game where racking up points unlocks upgrades and such, or helps you build a space station or some narrative thing.
Good luck.
well.. I have put achievements and leaderboards and I dont think people give any importance to play services and the game got gradually harder if you score more. I want game to be hard enough so that every point felt rewarding and player learn to play the game but I'm afraid that the game become so hard that the game become unplayable.
and yess game is inspired by flappy bird and jumpy tile
