I'm ending this day with a nearly finished player sprite (idle, walking and jumping animation included) and the sprite for the cat that still needs a lot of work:
Conclusion for today: I have heavily underestimated how much work it is to create the sprites, but I guess I'm having fun trying to make them as good as it is possible for me. I've always been bad at drawing, so I should've known that this wasn't going to be easy. However, I'm still very much enjoying working on this thing. :)
Tomorrow I want to focus more on the programming side as well as some level design.
