Feedback Maybe? That would be nice...

Which resources do you need?

Well, as the very first thing: I need the old sspp03 sprites, from which a couple sprites were used in the Clickteam game Brothers in Charisma. Then, I also have no idea, which game has got good cat sprites? If I would have had cat sprites, which included standing, walking and meow-ing, then that is already enough for me (I would then just recolor them into robotic cats).
And the last thing regarding sprites: The guns from Metal Slug. I already have Heavy Machine Gun and Rocket Launcher, but nothing else (and I want to include Flame Thrower, Shot Gun and Iron Lizard, aside from the default gun, of course).
Aside from that, since this competition wants me to use a self-made engine, I decided to do that (albeit with a bit borrowed code for the collision and variable movement part, because those are the only things, were I know how it works, but still cannot replicate it with my own code).

Quick question, are teams about to submit to this or is it just individual?

Thanks, I could try.
But I still need the sprites of sspp03 and the Metal Slug guns.

*still no sspp03 sprites and no Metal Slug gun sprites*
Okay, that's it. Since someone already dropped out of this competition, I'll drop out of it as well.
No sspp03 killing "robotic cats with eye lasers" while using a Rocket Launcher from me.

If I may offer some advice; you shouldn't rely so heavily on sprites from other users and games that you're completely dropping out of a competition because you didn't receive them. Get creative! Make them yourself, or maybe refine your design.

I'm sory, but spriting something from scratch is something outside of my ability range.
Sure, I can reshade/recolor NES and and Gameboy sprites, and I also can do at least some frankenspriting, but I cannot sprite anything from scratch. I just can't, no matter how hard I try.

Why did you think someone would make sprites for you in the first place. You can't just expect people to help you.
