Celestial Raid is a single-player, vertical shmup created using Game Maker. It contains old-school shooting with some bullet-hell elements. Currently the game has 6 missions with 6 bosses and 2 upgrades for the ship.
This is the first game I make and if you like it, I plan to add more contents e.g more ships, upgrades and branching paths for non-linear gameplay. Feedbacks are very welcomed.
