It's more than that. I reworked the entire animation system because the previous version made it so that i have to manually insert each frame for every animation and color variant of the animation, but it's much more efficient (and clean-looking) now.
There are also 2 new "features" (idk if 1 of them is considered a feature) in the next update which require a lot of animation time, but i am sure that people who already like the game will enjoy it.
Lastly i have to focus on the backgrounds. I know that player probably don't really care too much about new backgrounds or slight improvements to old ones, but i need to do it for a portfolio piece for a job that I'm trying to apply to, so it's unfortunately not optional, though i will try to focus on other stuff first so that i can perhaps release the update in 2 parts (1 with the new stuff, and one with the backgrounds).
I'm glad that people are still playing, and over the last month i have been working on the game a lot. A new update IS COMING, i will try to finish it as fast as i can, but i also have a job, so i can only work on it in my free time.
