oh sweet you made it to steam store man!!! all you need now is to sign up for next year deck building festival and i can see your success, dude. keep it up my man
also also, one thing i see and notice in games like slay the spire is sense of progression.
so i hope in steam launch you got some cards locked by either winning a run or by doing certain task such as win the round using 3 cards as an example. also stickers to unlock too cuz that would motivate people to get them
A couple of set of starting deck to unlock is a good one as well. Your game doesn't really have main character so I wouldn't want to focus too much on that
Curious to see what starting deck you plan to brainstorm and whether or not you want starter deck to be new cards or existing cards (I prefer latter and having few starting deck option would increase more things to unlock, such as "win this run using this starting deck")
