Pretty nice game so far! played until Heresy but will finish it soon but before that I have to give my feedback!

There's a lot of things to compliment:

• Coyote jump : very very useful
• Good Story : very moving, especially at times when the texts just moves by itself since I can eat some snack while reading
• Good Art Style: really nailed the nature of the game, and I believe everything was original at least for what I've seen! Also when the player is falling the player looks down.
• So much mechanics: every chapter has me intrigued with the possession mechanic especially the climber one
• Very good audio : music fits, has different audios for all characters, so much audio added compared to any of my games which is a good thing, really sells the dynamic
• Nice graphics : Nice fog effect, and  I especially like the intros to each chapters, I like how the color of the text is not full on white but yellowish, but yes I'd generally avoid mixing pixel and linear fonts, it generally gives off "something's wrong vibes"
• I could list a lot more but that's gonna be the end of it.

There's a few things to work on though:

• Noise Texture : maybe you have used this I just assumed because of the fog effect, but something inside the game is slowing me down
• Fast Enemies : jumping over them they instantly turn and chase even if I'm still in the air
• Lastly, delta time: so I have a suspicion that the Falling mechanic uses delta time, but the coyote jump didn't, or maybe it's the opposite, because since my game runs below 30FPS the delta time tends to be wonky(can't explain much about Delta Time here so try understanding it).
• That's all things that are affecting gameplay :D

Suggestions on what to learn and improve:

• Lerp: a platformer should have a speed acceleration and deceleration 
• Lights: improves your graphics
• I'll be playing more of the game so the suggestions won't be completed!

actually, i think first font is kinda doesnt match the game, you should learn text presentation from games like hollow knight, also game really dark and its hard to see enemies, try to add light source on character ,inputs in game kinda weird sorry, why i should jump on W and not on space or maybe all inputs should be on ASWD or arrows, also i have no strong motivation to go further as a character, there no exploring feel in game, but i think its great work after all, you should prqactice more in all sort of things but mostly on game desighn
