Many update happened since 1.0.4, but here is the important things:
- Change how the game handle memory, now it is more smoother
- Fix crash bug at Mac OSX
- Added Steam Achievement refresh button (in case you completed Boss Challenge without internet connection)
and some stage design changes so the secret is more visible, and many bug fixes.
- Boss Rush now unlocked when all other challenges are unlocked.
No need to clear Bonus Game anymore (Bonus Game would be just a bonus)
Thanks for the report and feedback~
Hope you enjoyed the game^^
