Well done!
That chapter intro was top notch, and set the vibe for the game so well. The different lighting effects once you're out of the cave were so cool also. I love the unqiue music for different areas and the dialogue you wrote for the individual bugs was great! Each bug felt like they had unique and interesting characters. I think the scope of this game was also very ambitious and I feel I only scratched the surface (I didn't actually finish unfortunately). The level design was also pretty great, with collectables showing up on the edges of the screen, hinting at hidden paths. I also love the little snippets of dialogue here and there as oshi notes some smell or thing she notices. A great touch!
My main critiques was with some design choices. I love unqiue lighting in games, especially when they're enhancing the aesthetic, allowing the player to immerse themselves in the experience. However, you may need to balance your use of dim lighting in areas of the game. The first chapter especially is quite rough with the level being fairly monochromatic and maybe too dim in my opinion. I also think there's a temptation to make things challenging when they don't need to be. I think the maze and level design, along with the charachters and dialogue would be enough, the addition of the scorpions felt more like a neusance than anything.
Also as a side note, I've read your comments about a map for navigation, which in my personal opinion may detract from the exploritave gameplay. Minimaps may draw the players attention away from the environment as they may just look at the map the whole time whilst they're navigating the maze. I think adding more landmarks and tightning the map layout may be enough to make it easier to navigate.
Great work here all in all. The best part for me was for sure the dialogue. <3
