This one popped out of nowhere as a "demo". I say "demo" because a lot of work has gone into this. It's 3 stages, there are 4 difficulty modes available, 3 weapons, you get 10 minutes of gameplay, and it's near enough feature complete. All that's missing is probably some more stages but compared to other Pico-8 single stage shmups, this is pretty feature complete.
This is a run of the Normal mode, which the game tells you at the beginning is pretty tough. And... it's pretty tough. There are two difficulty levels above which are a bit insane, but I managed this one just barely at the end. It's mostly a Touhou clone, but I did make sure to call out Alfa System's Castle of Shikigami and Sisters Royale since with the weapon I chose, a homing option, it does make me think of that game a lot before it goes full Touhou in the second stage with the scrolling trees. On that note, it's a Pico-8 game which shows that limitations are mostly aesthetic driven because there's a lot of scrolling, a lot of bullets, and not a hint of slowdown, it's a modern game with a retro look.
