Hah, dont worry about being too critical or negative or something. If anyone's gonna be the unpleasant negative one, it'll be me. Including about my own content. That stupid Mirror boss for instance... not even going to go into that right now, it just irritates me. Probably going to deal with that particular ball of annoyance later today finally.
Anyway, to answer some specific points:
1. Ship speed, that's actually some of the only feedback we've gotten on this element. It was only the Black Knight that seemed okay? Granted, ship balance is likely to change as time goes on (already has a couple of times) but I can see this is something to keep in mind.
2. Enemy bullets lingering... in certain cases, this is absolutely intended. Though, that specific one that just causes the crazed blue bouncing maelstrom, that stupid thing was one of the most recent enemies added in. Chances are, I probably just didn't catch that issue with it when I was testing the thing. I'll try to remember to have a look at it and see about giving it a less stupid number there. Bullet cancelling isnt likely to appear too often in this game. The structure of the game would make it supremely OP. If it does appear as a function the player can activate, it'll likely be one of those one-time consumable sorts of things, like the chips.
3. Getting stuck in walls, known glitch right now. Pretty annoying, yeah? There isnt any immediate solution to it, sorry. That'll be for Chris or Keith to deal with when they have time. Certainly out of my realm. As is the usual for Arcen though it's likely to be fixed pretty darn quick.
4. The teleporter bit... you know, I hadnt thought of that. I have gone and made this Mantis report:
https://arcengames.com/mantisbt/view.php?id=17940 based on your feedback here. Hopefully, that concept will solve that problem. Nobody likes taking cheap hits due to something like that after all.
5. If you're finding any very specific rooms that are giving you this issue often, try taking a screenshot or something of it if you would, and showing it on Mantis. There's a ton of rooms, and it's very hard to catch issues with all of them. Anything you might be able to point out would be helpful. However, some of it can also be due to enemy seeding right now; mostly, it's absolutely all over the place. Only a few enemies and bosses are actually gated by floor number, and some may turn out to be in the wrong category. I dont intend on setting most of them up further until more of the game mechanics are in place, so balance can be determined, so right now, that's a bit messy.
6. I agree on the beam traps there. I have made another Mantis report about this:
https://arcengames.com/mantisbt/view.php?id=179417. Energy weapon balance is absolutely all over the place right now. Consider it very, very early. I honestly think certain aspects of the energy system arent working out, to be honest. A couple of things I might bring up with Chris when there's time, so it's possible that the system may be altered later on. For now though, if you have specific thoughts about any specific item, feel free to post them up on Mantis to make sure the devs can see them.
8. Main weapon bit, I have no idea. Not something I've heard anything about internally, so I've no info on that.
9. The rebinds will probably happen sooner rather than later, I'm sure.
So there we go! The feedback is much appreciated. If you find any other issues, however small, feel free to bring them up. Some things are best posted on Mantis, though of course they can be discussed here too if you want. If it's specifically related to enemies/bosses/bullets or things of that nature, that's typically my realm (or my fault, depending on how you look at it), so feel free to just bring it up on here, I check the forums often. Certain enemies and bosses though, right now, have issues that I just havent gotten around to yet. I was GOING to fix a bunch of them today, but noooooooo. Had to drive out super early to the DMV and sit there for 10000 years, because that's what a DMV is for.
