I shall lay out my first 2 hours of impressions in point form.
1. Movement feels tight. I like it. Please KEEP stopping fast. This is crucial to being able to dodge a lot of the complex patterns. The initial build up of movement feels a teeny bit too slow.
Hah, I knew I wasnt going to be the only one that'd think this way.
That being said, the "altered" version of the movement shouldnt change the balance at all.... I cant imagine it'd be so extreme as to do that, that wouldnt be fun for anyone.... but this just reiterates what I keep saying about making it an option.
For the bosses: Yeah, I only just made that change, they sure aint perfect yet, and one in particular is a bit broken. Their original difficulty was just much too high for most people. That being said, I havent exactly removed those harder versions; they're still intact, I just need to re-integrate them, which I intend on doing today. Should be nice and easy to do. I hope. Once those are in, some feedback on them would much be appreciated. Just be aware that the game isnt meant to be like, stupidly difficult to begin with. There's some definite shmup inspiration, but we're not looking at quite that level of difficulty here. ....for now, anyway. The highest difficulty setting, "misery", just might end up that way. Or at least, it probably will if I'm allowed to do that with it! But for the other difficulty levels in the game, they're not meant to be THAT hard. But yeah, whenever you get a chance to fight the tougher versions of the bosses, which should appear on "hard" difficulty or higher, let me know.
Ship size, that's not set in stone yet, including it's hitbox. It's looking like it might be due for a reduction.
Enemy bullets vanishing, in many cases, that's entirely intentional. I'll have a look at the ones that fling the knives around though.
Glad you're enjoying it as a whole though! And thanks for the feedback.
