Hey
grandal wow, I talk to you in English so everyone can understand. As I made clear in the changelog, I only updated the sprites for this release (that's why it's called v0.2.9 and not v0.3). As you saw that demonstration, I worked on other things too, but I didn't get to implement them for this update.
I'm sorry to disappoint you, but please bear in mind that I'm not working on the game full time, and until last month I was still in the process of getting my degree. To make amends for this, I paused last month's pledges for my supporters.
The camera is twisted to fit most of the drawing on the screen, it is a stylistic choice. It's drawn like this, I can't just straighten it out. It's the first time I've been made aware of it as a complaint, I'll ask others to see if it bothers them too and see what I do about it in the future.
I use Koikatsu as a base, but the final piece is made by hand.
