I’ve been thinking about how to make the overall gameplay experience in Aeon Rivals more satisfying. I ultimately decided to try and rework the Style and Combo system. I’ve decided to do away with the Combo system in favor of a tying it together with Style to help both simplify game concepts and enhance battle flow.

Instead of Style slowly increasing when you alternate attacks, the Style meter will increase no matter what moves you use. Each move will also have it’s own Style increase multiplier, so many characters will be able to access their Special attacks much faster than before. As soon as the Style gauge is full, the character’s Special will be ready to use. In addition, using your Special will “Rank Up” the character’s Style level and increase their attack modifier. Each Style rank has it’s own unique color and be increased up to five times.

This new feature will be available to the public within the next week or so. If you have any questions or comments feel free to let me know on the forums on in the Discord channel. See you there!

Update [1.6.3]

Version 1.6.3This release fixes a few things adds a couple new features, including variable height jumping and the Dark Zone Gateway.

Dark Zone

This Gateway is in early Alpha stages, but it should be able to accommodate up to 20 users at a time. The new room contains stronger than normal Celestians, but always returns rare rewards. Gateways are only open at select times, which will be posted via the official website and social media. Please invite your friends and help us test out this new feature.

Variable Height Jumping

I completely rewrote the jump code so that users can now control the height of their jump depending on how long the button press is held. This makes for better control of your character and improves overall fun factor. A few changes were also made to auto-jump and double jump mechanics.


Horizontal hitbox sizes have also been greatly reduced to make it easier to avoid getting hit in close quarters. On top of all that, KeRobo has a new upgrade that gets rid of his fear of slopes.
