Good job! The gameplay is very engaging and challenging. The player gets really nice positive feedback on his actions and the music is good. But I have some complains(hope they'll help you to improve): There is no quit button in the main menu - small detail but it will definitely help. It would also be easier to aim your dash with mouse. And I'm not sure how the game relates to the theme(or maybe I'm just dumb).
I've also experienced a major bug when I started the game for the second time: the UI gets weird and the text is not displayed, icons are replaced with some crazy glitchy lines.
But overall experience is very nice and juicy. Make sure to try my game! Basically Johnny is split to two parts - one trapped in a top-down perspective and the other is stuck in a classic platformer. Try to connect them :)
