Is always good to see people making Ace Combat-like games. Still, this one has a lot of work ahead:
-Controls are mostly terrible. Pitching and releasing the stick makes itbounce like a rubber ball. Same goes for yawing. Going guns feels impossible because of that, so you might feel like waiting for your missiles to reload.
-Enemies are guaranteed to use flares every first time you fire a missile on them and will do it again as soon as their flares reload. Not only that, but their reload feels quite fast compared to the player's.
-Upgrades and weapons take away the score multiplier. A target worth 1.000 points might lose nearly half of its value if you equip perks. If points will play an important role in the game, then it means players can't add better gear for better performance on harder stages without being punished for doing so (and the game gets quite unbalanced pretty quickly).
-Different missile types will cause different amounts of damage, but given the sheer amount of enemies on screen, that alone breaks the game even on lower difficulties. that's a second punishment added to the already existing one on your score. basically, every missile except for the first two are useless because of how low their damage actually is. Considering the flare spam of enemies, as well as their large numbers, latter missiles must be more powerful despite their special abilities.
-Flares take an eternity to reload even with the increased reload perk, and mobs will mostly target the player's fighter. Maneuvering won't work most of the time to dodge so, if enemies are on to you, you might as well give up.
-There's no pause screen or any other way to return to the menu to swap weapons. If you want to go back, lose a get the game showing your failure on screen once again.
Overall, it's an unbalanced game with god awful controls. Honestly, this one is a pass for me.
