Hmm.. In my own subjective opinion, your Engines page seems cluttered, has multiple redundant elements, and has clashing contrasts. To name a few:

-You link to your tutorial series four times. Once is enough, and you can embed the playlist in the screenshots section at the top starting with the trailer.
-You have multiple screenshots embedded in your description text section, and in the screenshot section. Try to keep screenshots/videos in the screenshot section only (the exception may be your free starters pack promotion on discord). The talking avatar images may be fine in moderation.
-Too many screenshots. Curate which ones best represent the capabilities of your engine, you don't need multiples that show essentially the same thing. Less is more. You may also not need the soundtrack or Starter's Pack 1 in the screenshots section if they aren't actually part of the bundle.
-The contrast with the animated images on either side of the page are bright enough to interfere with the more subdued darker color's of the central page. Consider applying a mask and dimming the brightness of those by 50% to draw more focus to the central page.
-I'm not sure you need a disclaimers section. Is there any particular risk for data loss that's greater than any other tool? If itch.io doesn't offer refund's, you may not need to repeat that, people can just check itch's payment policies.
-You can have the licensing section title be the same as the other white titles aligned to the left. Also, instead of embedding all the tileset buy links included in the bundle, just add the bottom text: "The assets above are included with your purchase of MonMae, and when purchased individually from the links, include licenses that allow use in any engine.", into the license section.
-Don't link to, or mention G2A. Its notoriously associated with key scalping, and your cross promoting a different platform. Leave it to your customers to find their own purchasing solutions for GameMaker.
-Your current dependency on GameMaker isn't clearly included in your promotional materials, as seems to be mentioned by others in your comments. You may want to mention that earlier in/throughout your description/title image to clear up any confusion.

Feel free to take any of this with a pinch/pound of salt.
