Thanks for the feedback and many many more for hosting Harold Jam for so long. I'm still shocked at how much everyone likes Alex. Writing him made me want to die at first, but at the end of the day he became a multi-layered character I'm actually proud of in retrospect.
What glitches did you notice when switching characters? Eventing the character switches wasn't too bad, but that was a last day change so something may have slipped by me. The Cores were a risky move and I almost did change their weakness to the same as every other enemy. However, I ultimately decided to keep their weakness and have a descriptive message introducing them hoping it would work well enough. I feel like for a full-length game that will be based around seven elemental colors, enemies need different weaknesses than the usual RPS matchups to keep gameplay fresh. One way to make this easier would be to do what Octopath Traveler does and show enemy weaknesses when you hit them with the attack they're weak to. UI prompts should've been a given and I still can't believe I didn't steal what Sawyer did in Rage Against The Dying with the matchup chart in battle.
Big question; what exactly did you not like about switching colors? This isn't a mechanic I can just yoink out of the game I'm prototyping; it's pretty much the heart of the game itself. With that said, it has plenty of room to grow so I'm eager to hear what you can suggest. I can gather that there's a definite lack of balance between each color, given some said blue feels pretty much worthless and you can pretty much sweep the game by turning red and spamming white attacks. (Kicking myself for not having Souls be immune to white attacks now. D'oh!) Because of this, switching colors to counter the enemy's type would be a waste of time when you have such a fast, powerful, and time-saving tool at your disposal. A lot of feedback I've been getting through the form suggests to keep colors more as elemental types than stat boosts, and given how each effect can stack and skew gameplay I'm tempted to go in this direction.
And yes, there are multiple endings. Try collecting all the Facets and see what happens!
