You can find the beta version at the semi-hidden itch.io profile here. At the moment of writing this the private beta version sells for $3

Also, you can join the project Discord, using invitation link : https://discord.gg/6Crvp6F5dj

And in case $3 happens to be a problem for you, consider sending a private message to me either here at the Enormous Elk site, or in Discord.
