Alternate exits in Bit Trip Runner 2
Solution 1:
Each alternate exit (marked with blue arrow) unlocks a path to one side level. This levels are not required for story progression but can give you the following:
- New playable character;
- New costume;
- Gold (thus increasing gold count to help open other side levels that require gold);
- Trophies\achievements (some of them require clearing side levels);
- Just fun from running around and jumping over stuff;
If you`re not interested in any of this, then taking blue route is not worth it.
