Android release + 4 new chars

Now on Android, with PC-Android crossplay

4 characters added: Fiorito, Sandalphon, Shalem, and Lucio

Game Design change: you now choose 6 characters- 3 frontline and 3 backline. Game still ends after 3 deaths, but now you swap in backliners to replace dead chars. No more scenarios where two healers slowly chip away at each other for 10 rounds because all the attackers are dead and you're waiting for the right energy to trickle in. (This change has definitely made certain characters unbalanced at the moment)

Various visual improvements, QoL stuff, and bug fixes

Thanks to everyone who's played so far!
