This game is overall very good and worth playing, but there are a few changes that I think can drastically improve the game. The first is to get rid of the bot respawn function. When the player notices this they compare it to other mobile games and assume it’s rigged ( it kinda is). Then when the player loses they blame it on the game and have a solid reason to delete it.
The other change is to improve how the cars interact with the player. There should be a way to recover after getting hit. Something like, click the top of the screen with your other finger as fast as you can, or swipe as fast as you can on the top portion of the screen.
I know this is a .io game, but multiplayer would drastically improve this game. As well as character selection and board selection. Also, possibly map selection.
