So nostalgic... I have a lot of old, blurry memories with this game, but a great story about how I first discovered it. It wasn't even on this page, in fact, it was on a Sonic flash game fan-page that I don't think exists anymore.
I was only 6 years old and didn't understand anything about RPGs, and since English isn't my native language, even less so. I didn't know they were fan characters and I used to confuse Kyros and Karen with Sonic and Amy... normal, I guess.

And I know it won't be taken into account anymore, but my highest score was 297111 XD
I'm still trying to beat it.

My score is 138040. Good game but it froze so I could not play for longer :( Thankfully, I managed to get Target to poison Exodus on the first go so that was lucky. Personally, I use laser and power charge with Target as apparently his attacks can miss. Kyros is usually just attack and heal with City Emblem being used if SP is full. Blade is a great healer and attacker. Probably the best character in my opinion (although they all have their roles to fulfil). Karen is pretty simple: use SP boost to get to lake emblem as fast as possible and if I don't have enough MP then I just use the MP boost. Once lake emblem reaches level 5 it's just attacking and healing from there. I use Roy's SP Gift to aid Karen but once lake emblem reaches level 5 it's just attacking from there. I try to keep everyone's health above 1000 HP. It is also worth noting that I only use Roy's castle emblem if Exodus has used a shadow shuriken so my team can heal why he is frozen so he can't do consecutive shadow shuriken's. If Kyros/Blade's MP is low then I just use slide kick/throw blade. If Roy's HP is low then I use his shield and if Targets health is low I do not use HP borrow. Hope this helps :).

Made it to ~60,000
