I definitely appreciate the extensive feedback! Both big issues you mention are indeed issues, and based on lots of feedback so far, they will be addressed in the post-jam build.
Hitboxes on some items are indeed incorrect and luckily are easily fixed. I will find a better way to handle the item scrolling in the future as I do still want to keep the dragging as way of adding more to the board. Deleting also will be added and was mainly an oversight on my part.
Glue will be looked at as well, and your point about it is a good one. I will definitely be changing it to be even easier to use while Krafting.
Even drawing / painting might become an addition (should I get the shader to work lol) so stay tuned!
Thank you very much for the awesome feedback as these types of comments help shape the future of my projects!
