Pretty cool concept, would love it even more if the mechanic focuses more on the surfing aspect., being able to float in the middle kinda take me out of the pace.
This might change the genre of the game a bit but perhaps make it so that the player propels forward automatically, this will require them to time their rotation to make the jump to the next surfing platform, hitting any white platform will result in death. Players will have a choice to either focus on completing the map, get as many points as possible or both. But that's just how I feel would make the game even better.
Overall a really enjoyable game with chill retro synth music to go with! Keep up the good work!
