Great concept and design !, simplistic yet elegantly executed. One minor correction that could have been done is the audio. I played this game with headphone, and it feels like the SFX & BGM moves along with the character i.e if the character moves from left to right the audio moves along with him from left headset to right and the BGM stopped playing in the final level.
As the character is always spawned left, I kinda feel my left ear ringing ../
Best wishes for the team and waiting for future updates !!!
