Hi WanderingDev, thanks for the feedback!
In response to your feedback, I:
1. Reduced the amount of text on the screen to make early gameplay more intuitive. As the player progresses more information / text is added.
2. Added "starter" filament and made the "buy filament" button appear only when the player first runs out of filament. This way it is very apparent where to buy more filament.
3. Buttons should no longer be able to "click through" to the shelves behind the buttons.
4. Added fullscreen button.
Added to my to-do list:
1. Only allow removal of object if there is space on the shelf.
2. Make the shelf organization system better.
Thank again for the feedback! -Steven
