not reading everyone elses comments so, if I post something already mentioned, sorry, but hey it makes it seem it obvious that it's noticeable rather than just parroted from someone else!
-two movement related things I think you should add- crouching *possible rolling, evasion and what not*. And an aiming mode, where you don't move, you just point your gun, you SORT of have it with C, but, that's only for diagonals... and you still move if you wanna aim the other way.... I also realize that you may be in the process of adding these, but I state anyways JUUUUST in case.
-I realize it's more work, but if possible try not just flipping/mirroring the sprite depending on direction, it's a small detail but, it's noticeable.
- ability to aim straight downwards mid jump. maybe not necessary if you aren't using high jump power ups or double jumps, but she gets some okay height as is, I can imagine wanting to jump over an enemy and shoot him in the brain.
Minor quibbling details- suggestions that you don't really need to pay attention to, just minor things to add if you're bored enough to get super detailed.
- i can't quite put my finger on it but shooting straight up looks awkward, I dunno, maybe the head isn't up enough or something.
-the pointing of the gun/dropping the gun arm could be a bit more fluid, as is, it's instantaneous which looks a little weird.
positives- ACTUAL movement seems fairly fluid, I don't feel any drag anywhere, which is important! the sprite looks nice other then the minor quibbling I mentioned.
It's sort of hard to give any real judgement and opinion on what would potentially be important aspects of the game as it stands now, which is sort of the risk you run when all you've got up is a single screen and a sprite that does some movin' and shootin'.
I mean for example I haven't the slightest idea of the power ups you'll have *movement type? if not, how do you prevent access to certain areas? straight damage increases/ changing shot types? if so, how do you plan on not utterly trivializing later random enemies. health? maybe even have random "upgrades" that make your character go crazy or something! crazy with power! maybe she'll start forcing herself on the enemies or something WHO KNOWS.*
