Is it really too late to change the enemies so they shoot projectiles you can dodge like this? It's still in Alpha stages.
I actually got through testing it out with slow projectiles just now. On the one hand, I like that I can now have actual projectiles that look different (so different weapons give you different attack styles, so to speak), and slower projectiles do give you a better chance of dodging them.
On the other hand, it was cramped given the size of the screen, which meant that I would have to pull the screen back to give you 'room to breathe'. That, though, made the game feel smaller. The bullets move slowly enough for you to just run away from them, but that makes rolling feel unnecessary since you can just run away from the bullets (though I was going to adopt a kind of "Lost Planet" system where the first part of the roll makes you invulnerable. That would allow you to roll 'through' bullets).
The enemies moved too quickly for the bullets, as well (i.e. you would shoot at a patrolling guard and he would literally out-walk them). I do like the idea and want to try it out, but I think I'll keep the system that I have for now. I guess I could release a video or demo and see what people think, though.
As for having to take damage, as I've mentioned, that's the case with pretty much every shooter game out there. If you play brazenly (stand around in the middle of four guards and shoot), you'll probably die, or at least take loads of damage. If you play cautiously, you should take minimal damage. That's what I'm aiming for here - there are at least two different styles of play currently. Be bold, attack directly, and patch yourself up afterward, or be smart and avoid conflicts, taking out enemies when convenient, or even not at all. I don't think I want this to turn into a top-down Contra (run and gun).
With the stealth elements and good level design, you should be able to play without taking very much damage at all (if any), and still feel relatively satisfied with the gameplay.
EDIT: Oh, and my brother suggested that I add some sort of visible 'lock-on' system for the robots. That way, if you see you're being targeted, you can roll out of the lock and attack. That sounded like a pretty good idea that might be worth investigating, though that might discourage stealth gameplay
@Squid Party - Thanks.
