nice idea

give you 7 outta 10.
I like the playing sequence, why didn't you upload it?!
I'd like to have it and maybe with you're permission make a remix outta it.
the game was cool, but there should be more upgrades added and more difficulties...
maybe you've just started, then everythings okay, keep up.

Good Potential

You have the start of a good game but it's unpolished. Maybe add varied enemies (that fight back,) power-ups, and some sort of objective. Maybe a tractor beam to abduct people for bonus points? A charge shot would be nice since it takes two hits to knock down a jet.

Well

-First time I played it, I skipped the controls menu by mistake. When I died, because I didn't know how to shoot. I was stuck at the replay menu. You should add separate buttons to get to each menu.
-Changing up the enemies is a good idea.
-Maybe have then shoot at you
-Upgrades!

Really though, this game is a good base from which to build on. So, I can't wait to see how this game gets even better.

Too little things

I really think the idea for this game could be really great, except there are way too little things. Adress issues such as-

-Art; having the same f22 all the time is boring; try to draw something original. also, try to change the enemy speed, as well as waves. get them to shoot lasers, rockets, etc. I mean, in real life, i doubt if you're a UFO, you'd die because of a freak plane crash

-Upgrades: Upgrade your ship! Make it shoot faster, and have add ons that actually show up on the ship, so an upgraded ship looks different from the first. Add coins/points with a timer, so there isnt just a kill quota: you'd also have to quickly kill the enemies.

Honestly, this could really be a great game, but take some more time; NG doesnt have a 'sale quota/deadline', so take your time.

umm...uhhh...
