Found an expoit where I somehow aligned myself between lanes, so I can run uninterrupted. Since enemies are limited to the 3 lanes, the in-betweens and even the side bushes are extremely safe. Also, I could sidestep beyond the bushes and fall into the void and game over'ed. Maybe add some wall collisions at the side?
Other than that, I cant really comment on the other stuff since my laptop runs the game really slowly even on low graphics. Goodluck making more games
