This is great, I love the style and the vibe.
A few Decker technical notes: right now, the text is editable by the user (i.e. they can type different stuff in the text boxes), if you change the text fields to "locked" then that'll disable that and make things feel a bit more polished.
Also, if you tick a box in the "edit project" window in itch you can add a "fullscreen" button to the page, which can make things a bit easier for those of us with high screen resolutions.
