Thanks for playing! So the difference between the two paths is that:
1. The Brave path is harder levels but you get equally good rewards!
2. The Coward path is much easier but you'll hardly get any rewards.
It's up to you to challenge the harder path which gives you higher jumps, and movement speed or go for the coward path which though easier in the beginning, will start to get hard in the last levels due to the lack of rewards.
The game's ending also changes depending on how many times you've chosen each path (you can change paths once per level at lights).
There is some issue with spikes as some users reported and we'll fix those by tomorrow.
