I got a feature request from a player asking for the option to disable power-ups in the Tail Runner battle mode so he could be able to play the game "Tron lightbike" style. In the patch I took this one step further so you can disable power-ups in all battle modes so you can also play regular Snake and use more tactics to win against your opponents. 

Contrasts on some of the power-ups have been improved as requested by another player. 

A bug that causes snakes to re-spawn when you added a new AI opponent has also been fixed. 

Keep sending feedback and don't by shy to send feature requests. 

Complete change log v1.3.5 

* Improved: Added option to disable all power-ups for people who just want a pure Snake experience, tactical style.
* Improved: Add more contrast to the slow down power-up.
* Fixed bug: Pressing Y adds an AI snake to the game in battle mode. But if there already was 6 snakes in the game then pressing Y caused dead snakes to respawn.
