Thanks so much! We're super glad you liked the game-- and I hope it stopped raining for ya! ;)
We do have merch of our games, but more so our solo games-- and making a hoodie like Issa's is actually a lot more work than you'd think it would be! We would need a huge budget that a free game like this just doesn't provide, but we're honored you like the design enough to consider purchasing it.
Nami doesn't have an online shop currently outside of her Redbubble, but I (DCS)have a shop right here. Have an awesome day!
