if you have a PC or mac ren’py is relatively easy to learn! i was able to make a pretty decent working demo of DRDA (on my PC before it died rip) including like a free time event system, a way of tracking chapters etc etc. it took a solid few months of practice and i would definitely recommend watching many many tutorials but there are free plugins and tutorials etc for it. and it’s all free (i started with 0 coding experience and found it quite approachable)
