Hi there,
I made a free shmup pack asset featuring all-you-need to pew-pew-pew https://moxica.itch.io/shmup-sprites
If you're looking for placeholder gfx assets to prototype or not found any fellow dev to team-up, it could help you I guess :)

Looking forward to seeing all the entries!

These assets and the sample game are pretty cool. Will you be participating in the jam as well? I’m looking for an artist to team up with.

Thanks!
I'm afraid I won't be available for a good part of the jam...
But I will post here if something does change!
