Good game overall. It gets too easy towards the end though. I found it harder to kill those mini ship generators when I had a weak ship than killing the final boss when fully upgraded.
The same happened to me, domovo2.
It stays glitched even after completing a level. The only way to fix it is to let them kill you, then using the "continue" option.
Nice game overall, some fixes would be nice though. i was playing the sea mission. At the end I had 5 fighters and wasn't able to win because the enemy had 1 submarine with 5 hp.
Not bad. Could be improved though. Adding more turrets would be nice, some are pretty useless (like the basic one and the rocket launcher). All my floors had lasers, machine guns and the one that pushes enemies back.
