Wow I didn't realize that it wasn't clear how you move much slower (like 50% of dual gun mode) with the assault rifle; I thought the difference was obvious enough considering I used completely different walking animation for the assault rifle and assault rifle alone. Double jumping with the dual gun sounds like a good idea - I want players to feel like "swift ninjas" when using the dual gun mode.
Oh wait do you know that you can actually shoot downwards? I suppose I did not make a level that makes it necessary to use that move but... you can shoot downward... and shooting downwards somewhat gives the player a lift. My bad for also not making it obvious
I don't think I will implement free shooting... this, I must admit, is the main weakness with pixel arts... It is impossible for me to implement such a thing with pixel art. m(_ _)m
Regarding enemies... I think a solution would be slightly more complex AI. The enemy should not notice the player all the time and perhaps add a little element of stealth... I think this is the main problem. This solution tho... is easier said than done... T_T
I just noticed that I might be able to take a few notes from the Metal Slug series due to the somewhat similar gameplay... that game also has similar shooting mechanics and enemy attacks...
Regarding gamepad... you navigate with the left analog. The D-Pad is for changing modes in the game while left analog is for movement -- perhaps at least for the main menu I should've made it possible to use D-Pad huh... ;_;
