Secret medals = boooo
Decent game. Boss fights weren't that bad. The bonus boss fight was easier than the single boss fight, because of the platform gaps in the first one.
Losing half your score each death? Ridiculous.
Medal system fuxxored. No hints whatsoever. What are the two blank signs for? Like the one in C4 or whatever, near the top, in the back layer hidden in a little corner you can fall into with other hidden gems.
I cracked open the game to get the secret medals, after completing the game, but was unable to find five of them.
Oh, bug: I got the Quick Like Ninja! achievement as I began level C4. Glitch! =)
1. No deaths. Complete all 20 levels without dying. (You're such a dick.)
2. Score. Get over 100,000 points (no one has over 100,000 on the high scores).
6. Congratulations! Complete all normal levels in one session.
9. Quick Like Ninja! Complete level C5 (fifth bonus) without taking any damage.
