восток рогалик корабль (vostok rogalik korabl' or east bagel ship) is a turn-based shoot-em-up made in 7 days for 7DRL 2018.
Apologies for any bugs, this was very hard to make in under a week.
Use cursor keys or W,A,S,D to move, Space to fire.
Firing activates any blocks attached to your ship: guns fire, repair units heal the ship, etc.
Ram (ramming does not damage you) or shoot an enemy's core to destroy it (the 1st wave of enemies take one hit to kill). Collect its left-over blocks by moving into them. You can only dock with green blocks in your power grid (blue squares). Extend your power grid by docking power cells.
You have limited fuel. Collect cheesium from green space rocks. If you can dock a Yendorium Reactor, this will not be a concern.
I've done some more work on this idea as sandbox game: Star Shaped Bagel.
