Some notes on my playthrough. I played up until I completed the first delivery that dripberg gives you.
During the tutorial I encountered a pretty nasty softlock https://i.imgur.com/xxKe6oA REPRO STEPS: start game, play tutorial until you get the message from the robot federation. After that message *make sure you keep the cockpit menu open* and continue flying to the planet. Upon arriving to the planet you should get the softlock.
When the game's window loses focus it should ignore keyboard input. When writing these notes I found that jacques would wander around the screen whenever I happened to type a 'w' 'a' 's' or 'd'. Gamemaker seems to have let you check focus with this https://docs.yoyogames.com/source/dadiospice/002_reference/windows%20and%20views...
The mouse controls don't work properly on this menu https://i.imgur.com/BQ9BBiS you can't click confirm or go back
During the tutorial I initially didn't realize that my coolant was low, so my engine just kept exploding every time I repaired it. I reset and made it past that part, and eventually realized that low coolant causes the engine to overheat. This might be made more obvious, like if you try to fix then engine while low on coolant there's a flashing red "COOLANT LOW" badge on the UI.
The menus seem to always put you on the first option when you press b to back out, instead they should remember whatever option you were previously on.
By rotating my scoops clockwise over and over again I was able to get my speed way past where it's supposed to be https://i.imgur.com/RUbrOPY This let me get to my destinations almost instantly
Some of the ui seems to sort a little oddly, and it is hard to read when layered like this https://i.imgur.com/Bkk7kJ2 or this https://i.imgur.com/pR9lkFZ
The clouds on planets look a little odd. They move along with the player instead of remaining more or less stationary (ignoring wind) with respect to the world. Also they seem to additive blend with the background which makes them appear to glow a little. I haven't used GMS but it appears they use bm_add (bm_src_alpha, bm_one) instead of bm_normal (bm_src_alpha, bm_inv_src_alpha)
The panning on some of the audio is a little aggressive (e.g. the second ship leak you patch in the tutorial), I think it'd sound more natural if the audio never panned left or right more than like 70% or so.
On a more positive note the writing really is quite excellent, all the characters are fun and distinct, and much of the dialog is quite funny. I really like the alignment chart thing, which makes me wonder how much unique dialog you'll have to write. Also getting to pick your ship is really cool. The plot starts to move along once you introduce general crumbbum and the robot federation, which acts as a solid hook into the inciting incident. The game is packed with appealing little details that make it actually quite fun to perform simple actions.
