Hey - thank you so much - glad you liked the game! :). For software, the game is being developed in Unity. Artwork was done in Aseprite. Art has just a dash of bloom on it in my videos/clips (can be disabled in options menu).
As for platforms, right now PC but I want to do a Switch release (and really anything else) but a shmup needs to be on a switch first and foremost. Real question is whether I port it myself or work with a publisher.
