A madlad done an Android port of this game (current version) from 9GB to around 900MB/1GB with a sacrifice in quality.

Regarding the port, there are some fixes need to be made. But for the person who created the port. It's a friend of sensitiveusername, you can join sens server and ask Moog (who created the port to Android) regarding the development of the port.
Edit: Moog created a Discord server in case if anyone wanted something to be ported. https://discord.gg/EpPDDtgF
