Greetings!
This halloween, a portal to a dark realm opened in Energy Tail!
A special challenge is waiting for you, with 13 waves - including an evil boss.
Don't forget to try it out, before the portal closes.
According to our estimates, the portal should be stable until the 7th of November.

All Changes:

• New game mode for halloween reachable over the main menu with achievements
• Fixing a bug where the player can not reach it's maximum speed when using the gamepad analog stick under some conditions
