Tin Can:
As part of a space colonization program, you board a massive transport ship ready to leave Mars, but its reactor malfunctions on your journey to your new home. Previous experience in the simulator has not prepared you for this terrifying situation! Stranded in an escape pod drifting in space, also losing the ability to make a jump to hyperspace, you realize there is no easy solution. You need to use your ingenuity to fix the system, assembling your own computer as you swap and repair the internal components of each cabin. If you're lucky, you might finally find a safe haven.

Starward Rogue is a bullet hell twin-stick shooter. Blast your way through a maze of monoliths, nestled on the side of a star. Customize your mech with a vast array of weapons, perks, and upgrades. Prepare for the dangers lurking in the depths of the dungeon.
