Version 1.15
- Pufferfishes were added, and can be unlocked as playable characters by reaching at least Level 30. If you were already at, or past, Level 30 before the update, just play through one match in any mode and win the match to unlock them. Auto-damage on physical contact; useful when you don't have any Energy. Can cause illness to anyone who comes into contact with them, whether opponent or ally. They lose health in land environments. Selecting all Fish/Sea Creature types spawns the underwater stage where they don't lose health.
- Cold-Blooded animals move even slower in cold temperatures, and even faster in hot temperatures, within limits. Their movement speed gets set to a fixed number in both cases, so all of them will move at the same speed in the same temperatures, regardless of skill level number and base stats.
- Omni-Species can change its attack type again. In a previous version, it stopped switching types as it was intended to, possibly due to a change in the attack and targeting system.
- Items are no longer gained upon winning, but Currency and Experience can still be gained. Currency can still be used to buy items, as well.
- Desktop icon is larger.

--------------

Other details from previous versions that weren't reflected on the desktop version until this update:

Version 1.11
- Misquito has a fully animated travel animation.

Version 1.10
- Flying uses Energy steadily as long as you're above the ground. Selecting to fly lower or higher is noted in the Battle Log, and resumes the game when selecting it from a menu. If there is no more Energy, the character will drop to the ground-level.
- Missed and blocked attacks are now indicated where damage is shown at, instead of the Battle Log.
- Credits further extended on title screen for software used to make the game.
