This is really good but it could use a way to control speed.

Not bad! I like a lot the performance of the game, goes smooth, little lag, and it´s not complicated.

Things to improve would be (for me):
Bigger arrows, to locate the enemy easier.

Make the crosshair to show if you have the enemy in sight, then shoot, firing and realizing that you didn´t hit the enemy is frustrating.

Anti Air Artillery (for the rockets#)!

Eliminate the timer.

Make a faster propeller moving, add rocket rails, maybe using real national insignias, upgrades (explosive ammo shels, more powerfull engine).

The inverted y axis is a little confusing to me, maybe have an option to change that? Decent attempt otherwise

Wow, just plain awesome, I don't even have to say it...you already know it.

This would be a fun game if
- controls were better. A way to invert controls. A way to use joystick
- upgrades/different aircraft.
