Is it just me or are some missions extremely hard to do?
I always get the problem that my front line just doesn't have the def to hold for more than 5 seconds...
I sometimes get hung up in the "Loading Explore report..." screen.
Other than that, I'd like to have a bit more versatility with my upgrades. Not being able to move them around without paying means that I have to stick with a build or be weaker overall - even if my original build sucks.
A level based skill tree with 2 or three branches would be great.
Examples:
Attack ==> Lasers, misssiles, but smaller paddle size and faster ball acceleration.
Defense ==> More balls, bigger paddle, forcefield, slower ball acceleration
Effects ==> Ball penetration, Fireball, multiple balls, ball catching.
Better reason to have levels.
There should be an explanation of the hero movement schemes. Kinda annoying spending the money and then finding out that your new hero is basically uncontrollable...
