To follow up further, if you have any interest in tabletop RPGs at all, not just this one, please let me know! It's a lot of fun, and especially right now during covid, a lot of people are playing online and it's a fun activity to do with your friends.
Obviously there's this RPG here, or lasers & feelings which it is based off of which is super simple and is linked in the description for this game. Despite the popularity of Dungeons & Dragons, I actually wouldn't necessarily recommend the current edition, as it's fairly complicated (and also not my personal preference), but if you did want to start with D&D 5th Edition it's certainly doable. There's an RPG called Fate which I think is another good introduction RPG. There's a website, drivethrurpg.com, which is kind of like the steam or itch for tabletop RPGs, selling mostly digital, but also some print options. Pixels & Platforms is not available on drivethrurpg, but plenty of other great games are available on itch and drivethrurpg.

Alternatively, you can check out r/rpg on reddit, or any number of other rpg subreddits such as r/osr (focused on old-school D&D). Also, I have a blog list on my blog with many other awesome tabletop rpg-related blogs. If you're the type, there's a whole rabbit-hole for you.
