Xeno Fighters R Showcase - Ships and Conquest Mode
The first Infinity War of SHMUPs, that started all the way back in 1998 and is still being developed, with the Game Maker Studio port being the latest release.
Instead of being a tribute to CAVE, it's a tribute to the Raiden series, with only missiles and lasers as your weapons, aside from your main weapon and bombs.
It also has a lot of stages to play, despite some of them not being fully completed yet (missing bosses, enemies, balancing etc.) and even now you get a lot out of it.
Conquest mode is basically freeplay/practice mode, where you get to play any stage you like with the main goal being scoring a lot of points, Arcade mode is like in Raiden Fighters Jet.
This video shows of Stage 1 with Amada Vipros, the boss is Techno-Ayako.
