Yeah, the game getting chonk is one of Arc’s concerns.
I mean, the published date in this page is misleading. The game has been in development since June 2019.
And he has been taking some care in keeping filesizes low, considering he has to publish updates weekly and due to his lifestyle, having good internet is not always guaranteed.
Arc is trying to keep the final game under 2GB. Other games in this ecosystem get quite large very quickly.
The RPAs are an option, but at the same time it’s not the idea to make the installation process too much of a hassle for the end user. Ideally, one could just tell them to download the PC version and use JoiPlay, but apparently that was also unreliable.
Up to Arc, I’m just answering because he sometimes takes a while to answer and I can cover some things on the question.
