Classic. Enough variety in power ups to keep it interesting for a while. I think the gun power up is a bit OP though it made it too easy. Maybe limiting the ammo usage some how could help balance it. Very fun!
Thanks so much, i made it on 10 hours, i did not have time to test difficulty , but any way it easy at start but after about 6 or 7 minutes that tanks attack rate will make survive is impossible.
