Hey, it's me again! :)
So I've played all of your game (including all the options) and it was tons of fun, I really like the part of the deal with the devil kind of thing (I didn't find any changes that saying yes to her does but I guess it's under development).
Although I had fun playing your (super hard) game I did had some issues playing this game so this is what I think you should focus on improving before continuing with the storyline:
- Collisions!! this is your main problem now because I often fell to my death because of a physics problem. Is there any chance that you are using a cube-shaped collision shape for the player? if so I recommend using a capsule-shaped collision shape.
- The controls feel slow and unresponsive, work on that
- The camera thing (you already know that).
- Add a shadow to the player, I agree with Pick A Pie on that.
- Consider adding some sort of checkpoints in your game, I would be super annoyed going back to the beginning if I am, for example, in level 10.
- When the devil guy talks to you, doing the dialog is pretty weird, make the lines change by time, not movement if you want.
Other than those issues you have a really good game, I really like the story and the concept!
Have (again) a good day!
