I'm SketBR, a solodev, and I've been working on Starfish ROOM: WELCOME TO LOOP ETERNAL.

It's a fast-paced 2D Musou/action roguelite inspired in VSurvivors, Bullet Bunny and Spent Shells where you play as Kibo Wave, a transgender catboy fighting hordes of monsters and aliens to unlock others ROOMS.

There are also weird random cards, combo abilities, dash attacks, dynamite, alien bosses, and an eternal loop system where eventually you have to face Boki, Kibo's clone from the future.
I develop the game as a solo dev using GDevelop, and a lot of my development has been done directly on an Android phone. It's definitely been a weird way to make a game, but I've learned a lot from it.
