could use some tweaks...
but let me firstly say that it was a great game.
the things that let me down were in the repetitiveness, really. beyond that, it's pretty well done. some notable fixes, i think, would include:
1) enemies who are "targeting" the player's ship should not count as having reached the planet just because they cross it. this would introduce a bit more strategy to the game, luring enemies around and then using your guns to target other incomings
2) drop the decimals in the money/shop screens. i know this is a minor detail, but it looks unprofessional, whatever that means on newgrounds.
3) sound options: either have better music, or a way to turn off the music (keeping sound effects might be a plus though). though i loathe to admit it, i'd rather be playing this game to some euro-techno beat than the music that is playing now.
4) accuracy bonus? you're keeping track of hits and misses, why not introduce that as an element of gameplay?
5) button remaps: at the higher levels, i'd rather my upgraded cannon be number one instead of 6. i ought to either be able to remap the keys, or, and this would be a great change to the gameplay: have a limited number of slots on the ship to fill. and then adding the new cannon, for instance, would force me to remove another of my older weapons. this would also introduce more energy balanced weapon loadouts. tying in with this is number 6
6)weapon groupings/quick changes: the freeze cannon is kind of pointless if it takes me too long to switch to it, fire, and then switch back to cause damage. i guess this helps to make the game more difficult, but it might also be cool if i could configure weapons to fire, say, every 5th or 6th shot.
well, i guess i had more to say than i thought, it's a good thing, though, i think your flash has a lot of potential and i'd like to see that come out in a game that the community might tag as epic. as it stands i don't think this one is quite there. i don't say that with hostility, though, you've done a great job here.
