I was going to suggest a "kinetic novel" or visual novel type when it came to interactive comics, like a one-direction/no-option VN.
Visual novels are not difficult to manage.
I would suggest the Ren'py engine (free), which many popular VNs use as a backbone. If the site allows it, the link is here:
https://www.renpy.org/
Ren'py uses Python as the underlying scripting language, but it's all scripts. It's not difficult if you can manage light programming/dev work.
If you need a GUI, then there's Tyranobuilder. Tyranobuilder is more popular in Japan, with built-in support for Live2d animated figures. I've been wanting to experiment with Live2d, but it's a subscription-based license. Not really willing to pay for that.
If someone could integrate Spine figures into Ren'py like Live2d figures can be integrated into Tyranobuilder, that would be all sorts of amazing. Not holding my breath, though.
There are other VN engines, but I don't have those and cannot comment on them.
