Update 1.0.5.3

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^^
