Cool game, the level design and ambience was pretty well nailed. The art was really cute and interesting and the sound and music design (loved the chapter 1 music) in general was really good.
I think in terms of the movement, a little more control or friction (specially while in air) might've made the precise movement less harder to maneuver. The levels were definitely way harder than they probably would've been due to this, but with more controlable movement they would probably be already good enough as is. The auto jump also might interfere with some of the platforming: if you have to react fast, a held jump input might just take you back because of it (most noticeable in stair sections like pre-server room).
A small personal nitpick for chapter 1, felt the spikes hitbox matches way too perfectly the spike sprite which makes some horizontal walljumping sections more annoying to deal with.
While i loved the respawn animation, at some points it respawned me back over some death pits or screen edges, so i had to react (wasn't sure if its just a rewind or a respawn on start spot). This in particular became a problem in chapter 1 where some times i spawn in the edge of a room which triggers the camera for the next room so i find myself wiggling around to see if the camera comes back to the current screen (mostly had this during the bottom section of the map near to the USB drive room and falling into the pre-server room). For some rooms also, failing at the end makes the rewind animation take quite some time to go back to start (or at least feels like) making every retry take extra time.
Had a hard time trying to read the dialogues with the letters appearing effect, felt like most of the times i had to re-read the dialogues to understand, and at some point directly started skipping some trying to get the full phrases. Also felt the voice actor clashed a lot with Mint and Doki voice lines (it was good though since it helped with reading Draken phrases quicker), both in terms of their voice line formats, and in terms of volume (the VA was way louder than the other lines).
The stealth mechanic was quite interestingly balanced, it definitely added some extra spice to the platforming and made rethinking how to navigate the rooms and when.
I'd love to see the project get continued later, got quite hooked and love me some good platformers and fun story.
