First of all thanks for this long comment! I really appreciate it.
I will work on clarity ASAP. That's why playtesting is so important. You suddenly see all the shortcomings you couldn't see yourself :D I will also add more clarity to the controls.
Yes, the sprite is a placeholder and good to know what Pixelation you liked. I will change the default to 2 and then people can decide.
I also like the idea of unique ressources, but it is not fully fleshed out, which makes it a bit underwhelming. I agree with you. In general the idle gameplay needs more depth. I played a bunch of idle games myself, so I can see that there is still a lot missing :')
I do understand your point with the graphics. I also feel like there is still a bit missing, but I also need more experience in that. I already tried a bunch of things, but learning by doing :D I hope I can still improve it or at least find some kind of way to make it pop out more :D
And good point with the new-game+. I already have some ideas to work around that, but you will see it in the next bigger update when there is more gameplay to it, so new-game+ makes sense :D
So again thank you for the detailed feedback. I will work on that!
