I've tried the recent update and here's some feedback!
+I've completed the first mission, the game's great! I'm not sure if the difficulty was lowered, but this time I thought more on upgrades and played in a more intelligent way. Still died like two times, but all fun!
+Speaking of lives, I got to have 5 revives, which I think could be a lot, but considering this is just mission 1, deepending on how fast difficulty escalates, it could be okay for last missions.
+Final boss looks so good and the battle feels epic. I'm not sure if deleting all enemies right when the final boss appears could be a good or bad idea; it keeps certain difficulty and makes you need to pay attention to the boss as well as the pink and elite enemies.
So in general I think the game is great for now!
