I've got no complaints about this game. I enjoyed the music, the art was good, it ran smooth and played rather well, and reminded me a little bit of the Sega Genesis helicopter games in the Strike series, which I loved. It was fun to get more upgrades and different kinds of tanks. Good job, Vitaly.
Final plot twist: Visitor is Christina's mom and is just doing this for the lulz since she's gone through so many lives in so many universes it has become a battle against extreme boredom
Dat feel when your army of expensive mages walks through the portal and disappears... why can't they just hold position and let the cheap guys walk through ;(
It would be nice if pilot's academy included at least one session about how you and your whole squadron shouldn't continue to fly into ONGOING explosions consisting of your entire force, so my units wouldn't kamikaze into their own chain reaction.
If you're having trouble on the last two levels, like I did, try using Ray as teamleader and Glenn/Selena as your members. You'll get lots of weapon drops with Ray so you'll max your weapons faster, which is really important. Glenn's skill will make you faster so you can dodge all of the obstacles later, and Selena has a full party healing passive that synergizes well with Ray's damage dispersing passive. Ray's flamethrower superpower is also great for destroying those pesky witches who raise skeletons before they overwhelm you. I went from getting annihilated on the first few screens of the 2nd-to-last level, to womping it all without anyone dying.
On 19, I couldn't beat it until I had maxed out everything, I put 2 rows of 5 mines in the very front, a solid line of tesla ground, a solid line of tesla air. I fired my tesla click in burst just to slow down the invasion, and saved orbital for a big group. My whole defense got wiped out and I frantically stalled with tesla clicks and placing rebuilt towers until I could do another orbital on a big group, then I mopped up the survivors.
