Didn't get too far before they shut it down.
The graphics and music were good, gameplay too. They made pixel models for he newer characters like lightning etc.
Gatcha wasn't that bad but it was still mobile tier game so, it had annoying bottlenecks that you could solve with real money.
Overall it was worth it for me personally, I'm sad that they closed the servers.
Only tells me to not invest much effort into the other mobile games, you never know when they will shut it down.
