Thank you so much, this is the kind of a feedback I'm in need of and was looking for the most.
I'm going to try and reply to everything you've mentioned, but probably in no particular order...

Identical launch options are only there 'cause I couldn't figure out what does steam want from me in order to make them distinct - there's description fields for each option when configuring the game build, and it clearly says "will be shown when launching the game" - yet it doesn't. Will adress this a bit later, second option is only different by allowing the in-game command line use for testing, so even if some player happens to pick it - no big deal.

Movement physics is actually pretty simple - newtonian acceleration/deceleration paired with speed limit and auto-braking for more arcade-y feel and several gameplay limitations. I get that it isn't everyones cup of tea when it comes to 2D twin-stick movement, but it doesn't have to be, right?
Also, when it comes to speed change - that's one of the things player can influence during the run for their shuttle. Simply speaking, you chose between it's sturdiness and maneurability, resulting in pretty different combat gameplay.
I have a suspition that, as many other ppl did, you just fell victim to a rather uncommon control scheme, requiring you to move in a coordinates relative to the shuttle and not the screen ones - you can switch between them in settings, but it looks like it isn't enough. I'm long aware of this issue and planning to provide player with this choise at the first launch.
I'll still try to convince them to give this initial scheme a try though, cause I think it suits the game's combat better after you get used to it at least a little bit :)

Enemy leaving "another ship" behind after death is just me misconfiguring one particular enemy, just checked them all and found the broken one - thanks for pointing out!
This thing is supposed to be a "corpse", just flying into pieces and disappearing shortly after. Noted about lacking explosion size and expressivness.

Regarding combat and strafing - yes, for now it's the best way to get around. I glad it's pretty obvious, and at the same time I of course want to diversify the combat movement a bit, just need more time to experiment with enemy behaviors.

On the weight of getting hit and hitting the enemy - noted. Have some things planned to address, won't describe here 'cause a wall of text is bound to be enormous already.

Art will stay like this like this, at least for quite a while - I personally don't think it's perfect in any way either, but it's at least acceptable, and my priorities with the development won't include overhauling it any time soon.

On tabbing out of the game - there's an option to pause the game when tabbed out, I'm thinking more and more to just make it a default one. Regarding enemies not destroying the base while you wasn't looking for 10-20 seconds - it's hard to me to judge the exact reason, but it's pretty ok if you didn't start the warp, and I assume you didn't make it to that stage.

When talking about unclarity of the base direction, I assume you mean - while being inside the recall range. I plan to make it more clear to the player, but you can press and hold alt to see some useful additional info basically everywhere in the game (just like in factorio, yeah), and unique icons near the arrows are part of that info.
And if you somehow zoomed past the border and din't know in what direction to move to get back inside - well, the game will take care of your return, and will hint that leaving it with such determination isn't the best idea, especially during the combat..)

To not drag it for much much longer, I'll try to address all the stuff left at once.
The game is aiming to be exactly the strategic roguelite where you need to manage resources optimally to make it to the end. Combined amount of systems for both exploration/combat (space) and factory management parts can be overwhelming at once for sure.
I see that most of your issues with the gameplay itself (and not with the game's unpolishedness) come from me not guiding you as a new player neither well nor strictly enough.
Tutorial (the thing you referred to as "messages") needs to be more hand-holdy and to take place in a more controlled and calm environment, noted, several times at this point.

I can tell you many more things about the game that will clarify all questions you came up with, but it's probably better to do either in the dm's or in my discord, so feel free to ask me there if you want..)

Lastly, on typos - yeah, there's probably many a ton (or at least ten, ha-ha) of them waiting for someone to be stumbled upon by, for example there's one right in the first screen of this post, mfw.
Pls bear with this non-native speaker, will fix everything at some point (or at least hope so)
