Overall this was a fun experience.
Story: Definitely a unique story with some interesting backstory that I was hoping might be fleshed out a bit and left me wanting to know more.
Gameplay: I think others already mentioned the acceleration was pretty high which made precision difficult. Also the player hurtbox range was pretty small so it was more challenging to fight quick battles forcing me to try to be more careful. Probably just needs a bit of tuning.
Having a lot of jumps was pretty fun. initially I tried timing the jumps to try to get as high as I could but eventually realized I'd get much higher if I just jumped as fast as I could.
Minor issue with an enemy dying outside the walls so the pickup was inaccessible, but because enemies respawn that's not really a major issue.
I talked to you in discord about the keyboard/controller issue. It was probably an issue on my end, but it wasn't super intuitive that the global option to use Controller didn't seem to override the player's save-game if they started a game with keyboard controls (then saved).
It would have been helpful if there was a better way to replenish life other than grinding droid/probes.
The ranged attack was really interesting but sometimes it felt like the range-aimer thingy wouldn't disappear fast enough so I could move again. this mainly impacted me on the boss where it seemed to stick on the range-aim mode long enough that I'd get lasered. wondering if maybe moving could insta-cancel the range-mode.
For the blocks that took multiple hits to break I thought it might be nice to make them change color or texture to indicate how many hits they'd taken (and when they were one hit away, make them look like the one-hit blocks maybe). kinda minor since in the jam version the blocks weren't a major factor.
Graphics: I think the overall graphical appearance was pretty consistent. I really liked the background (and the parallax in the far background). The droid/probes were simple but looked fine. I liked the elevator drone.
Audio: I really liked the music and I think it fit pretty well for exploration. the sfx for the player were pretty good and I liked how the boss had its own music. I agree with comments that it might be good to have some sort of sfx feedback for damaging enemies. I didn't realize I was even damaging the miniboss till I finally noticed the enemy health bar and that it was depleting. Same for the boss; might have been nice for some audio feedback since you could hit the boss offscreen and only knew you hit it if the health bar went down.
Enjoyment: I enjoyed playing and was glad that I beat it. I felt like I'd accomplished something which is a testament to the challenge feeling fair and interesting. I'd love to play an updated version if you keep working on it for SMVM
