Very Strong Submission
Nice stuff you've got here. You quite obviously put a great deal of effort in to this, and it truely does show.
Although I've only played at a small ammount of Ikaruga, you did a very good job blending it in the the classic megaman feel. The recolouring of the sprites was done cleanly, and was overall nicely done, visually. I would have perfered a slightly more interesting background, but I wouldn't bash you for what was there.
Gameplay; well, you did do a good job, but you still have some kinks to work out. I tried repeatedly to clear the second stage with no sucsess. The reason, being the room where you encounter three 'up' lasers over pits (Red-blue-red) that press you towards spikes. The first one works as I would expect, but if you tried to go back through it, or in to the next one, normally, you'd 'jump', key-press or not, at be killed immediately or with no time to make it through or back to try again. I noticed that if you try to jump and fall in to the laser you won't get bounced up, but the hit detection on the spikes is much bigger than the graphic, so it's a percarious move. I even tried going under without sucsess. The unsolicited 'jump' also occurs in a few previous screens, but only at this one (that I saw) was it leathal.
Additionally, there are the aforementioned bugs; Bullets scroll with the screen, double jump on screen auto-scroll, nothing serious.
I'd really like to see the ending, but I guess I'll have to wait on an update.
I also found it a bit sluggish in movement, and various thinigs had been left out, perhaps unnessarily (sliding, some sfx), but all in all, it's very good.
I look forwards to seeing any future updates and projects.
