plasma ball
plasma ball is now live, but it's still in beta
still needs
new graphics
damage balancing
fast decay in mob shields
player angle rotation speed while firing adds to fire speed
tech upgrade to get electrical arcs that randomly damage nearby mobs
current tech synergy
capacitor bank,plasma jet(range?)
reservoir level is less crowded, so you can dodge mobs easier
horizontal flipped version is so reenabled
pure science renamed paradigm shift
difficulty scaling for heal and mob damage reduced 2%
some possible bug fixes, I don't know...
