Once I got a hang of controlling my momentum, this game was pretty fun! Since this game is pretty difficult at first, especially when trying to understand the controls, I feel that the game should have some sort of fast restart button or have a quicker transition from the lose screen so as to not make losing feel as punishing. Also, unlocking a new character killed one of my runs due to the intense slow down which broke my flow. Overall, nice work!
And the fact that this was made with no engine is super cool!
