Thanks a lot — this is exactly the kind of feedback I was hoping for!
All three are fixed in the latest build:
1. The seed now sleeps until your first move — a short "Move to wake the seed" prompt, then the clock starts.
2. The GDevelop badge no longer covers the editor tools.
3. Added touch controls and gamepad support (the level editor still needs a mouse — noted on the page).
Going to play Thin Film next — I'll leave my thoughts there!
