Wow, i've really enjoyed the game! I appreciate different aspect of movements and how can you improve when you know all of them (also pretty sick tutorial, i like so interactive ones). Only downside is when i feel that i need precise movement pattern and when it's difficult to do from checkpoint (at Course before 3 dots kinda hard imho), more freedom at this would be great (mb even alternative ways?). But core gameplay is great, music and sounds are also good, so just continue to work on it, should be cool :)
Btw do you mind to share how have you implemented leaderboards? I'm working on my own version but now i have only local ratings, would be cool to know how you did it
