Thank you so much for playing! This is the first game we've ever made (and first game jam we've ever participated in), and we're really glad you enjoyed it.
We agree that the ship is a little slow, and planned to speed it up by 10-20%, but unfortunately ran out of time before the jam deadline. As for controller controls, that is something we also started working on but unfortunately ran out of time for. A shame, because playing shmups just feels so much better on a controller. We also discussed a score system as a great way to add replayability and a bit more fun factor, and that's something we'd like to integrate soon as well. Thank you for the valuable feedback!
