Nice work, my first 3d metroidvania also was basically untextured, everything just takes soooo muuuuuch time. Overall, the controls felt pretty good, some stuff felt a little off but overall worked well. It think the biggest thing missing is the clearer feedback. Initially there are locked doors, but then later there are doors you just walk up to and I don’t recall any distinction between them. Maybe it was your intent, but I think the telekinesis movement is too slow, combat was mostly running away. My first encounter with an enemy was confusing, I set my familiar into the darkness and they had come out larger and red with some power up. When I got the smart interaction, I didn’t realize the blocks to get out were what was triggered (also, loved that little puzzle!).
Possibly of note, I made it to the end but didn’t get the glow or glide upgrades. The familiar interactions were cool, I can easily see expanding on that for a lot of puzzles. Even though it’s proto assets, I still appreciate the initial decoration, I rarely leave any time for that and just end up with boxes. One thing that probably bugs mostly me is the straight hands, just curving the fingers slightly into a more neutral pose would help a lot.
Keep it up, looking forward to more!
