ROCKBEARRR! ! ! Absolutely adore this, couldn't believe my eyes when I first saw it. A PSO2 fangame? And a fighting game at that? Incredible! I've played through versus with a majority of the characters and I can say that it's super fun.
The map variety is unbelievably large too, plus the musical flourishes you add to the end of a round when certain characters win are lovely. It still shocks me how much love and effort was and continues to be put into this game, I was fully expecting this be abandonware when I stumbled upon it out of nowhere, but nope, you're still going at it, and I have nothing but respect for you.
If there's anything I have to say with regard to gameplay, then the Just/Perfect attack bubbles or some indicator that you can repeat attacks could help. There's an issue with the characters getting stuck floating on top of each other too, would definitely help to have the characters slide off of one another, especially on the ground, maybe you'd be able to footstool another character if both are in mid-air. You're completely unactionable except for jumping when in mid-air, so getting stuck while floating on top of others isn't fun. There's also a tiny spot on the wall on the left side of the "Training Area" below the ledge where Rheo managed to get stuck.
All in all, an incredibly fun experience! Certainly made me smile many times and let me recall a whole bunch of fond memories. Looking forward to whatever you continue to produce in the future! Thank you for your work on this fan game!
