Thanks - you were right, and I checked it rather than assuming.
You found the actual snag: I was describing the full pack on the free sampler's page and making people dig for the difference. Two of the previews were flatly wrong.
The caption read "20 animated creatures - 4 directions - 5 animations - 1440 frames" on the FREE sampler. The cause is in my generator: a shared "cast preview" helper draws the paid product's subtitle underneath whatever title it is handed, so the free sampler inherited the paid pack's numbers. The walk-cycle preview had the same fault - it claimed every creature ships "idle, walk, attack, hurt and death", and three of those five are paid-only.
Fixed, all of it:
1. Deleted the preview carrying the 5-animation / 1440-frame caption.
2. Rebuilt the walk-cycle preview. It now reads "20 creatures - idle + walk - 4 directions - 640 frames", and says underneath that the full pack adds attack, hurt and death. Labelled the way you suggested.
3. Added a preview that is exactly the thing you asked for: a side-by-side of FREE SAMPLER against FULL PACK, with the paid-only rows marked. The two are now separable at a glance instead of by reaching the bottom of the page.
4. Reworded the opening paragraph. It now states the free contents up front: "This is the free sampler: idle and walk animations, 640 frames, 16x16 and 32x32. The full pack adds attack, hurt and death for 1,440 frames in total."
5. The process paragraph now says all five animations line up across the library, then states plainly that the sampler ships two of them - so "five animations" no longer reads as a claim about the free download.
WHAT THE FULL PACK ADDS is still there at the end, but the distinction no longer depends on finding it.
One thing I owe you: I had read that caption several times and it never registered, because I already knew what the pack contained. You did not have that context, which is exactly why the feedback is worth having. Thank you for taking the time - page-only is what I asked for, and it turned up a real problem rather than a style opinion.
