My first game finished on the Steam Deck. I have no memory of receiving Bardbarian but it was verified on the Deck. It played really well.

It's a tower defense, but you are able to move around to avoid bullets. You don't directly attack; instead, you build a team and buff them as a bard. There's normal and insane difficulty plus two extra modes for rewards. It's fast paced and easy to learn. You want to earn gold, spend your gold in shop, and then jump back in! It can get repetitive and grindy to unlock everything from the shop.
