Wow. Thank your for your long and valuable feedback. I just wrote a feedback for your game :D
Did you finish the game? Because then you know why the tutorial is so long ;)
Some feedback to your feedback:
1. You are correct that the credits button looks like a menu, because it's the same that is used in the pause menu :D We were a little lazy there and thought it was ok. But I will consider your feedback for my next game.
2. Hmmm... That's a little weird. I got my text proof-read two times. Are there really that many mistakes? I was sure to be quite correct on the dialogues.
3. Yes, I used cinemachine and I tweaked the camera a lot. I even tried out the look ahead stuff, but it had some problems. It was very hard to tweak for the moment the player turns around. You could go with a slow transition to the look ahead in the other direction which feels weird because it takes so long. Going with a fast transition which would help the player navigate was making me really dizzy when switching left and right a lot (wall jumping for example). Additionally it had the weird behaviour to return to the center of the player when I jumped without moving. So I had to ditch that part and go with the "backwards" camera approach. I would say the game is suprising the player from time to time :D
Yes, we are very proud to have created this game in just one week. We had some struggle with the theme and low motivation at the start, but we sit through it and it was worth it :D
