wow! I'm glad that termux exist, it's such an amazing tool!
I don't know if you might find it interesting but I made an open source coding tool and framework for Android that is pretty fun and fast to use. You can code using the phone or a computer using a remote editor throught Wifi (no internet required).
It comes with lots of examples and remixing them is quite fun to get quick and nice results.
The "compile it your self" link in the README (https://github.com/victordiaz/PHONK/blob/master) is a 404. (also, it should be "yourself"), and the landing page site header is cut off on mobile, so the GitHub link doesn't show up.
Based on the description "Connect your computer and Android to the same WIFI network" I'd assume that you need at least two devices, but from your comment I gather that's not the case? Maybe you should clarify that on the landing page.
