Finished it, finally
Bubble tanks, the original, was a great game. This is just a decent game, though.
Customization, while a nice surprise, lets you build very broken things. Like, placing as many mega cannons as you can at the edge of the class 4 bubble, then just scooting on through.
What really held this game back is the pacing. It's so slow! As said before, having to clean up the tiny no-threat enemies really adds to the time spent in a bubble, and detracts from the action.
Everything has waaaaay too much health, usefull upgrades are too rare; at one point i was convinced i was doing no damage to a ship because i'd been shooting it continuously with my highest DPS weapons, because nothing was happening. It's a shame enemy tanks don't devolve as they lose health, because that stopped them spamming up the feild, and gave you a sense of progress.
And was having that 'not enough points' error take up so much time a good idea? No. Place a part slightly off-centre, and you have to sit through a redundant message on an inactive screen, every time.
I did finish the game, but looking back, I really shouldn't have. So much time gone.
The overall concept was nice, but the actual gameplay holds it back.
