Really nice take on the limitation. I feel the default control settings for keyboard could be improved (but thankfully they can be changed in the settings!) and it also needs a bit more content.

Thanks. Glad you enjoyed it. I'd love to know what you think would be better controls for the keyboard. I actually changed them a few times through development because of playtest feedback I got. I prefer using my controller personally.
More content was planned, but I ran into some bugs that prevented me from finishing what I had planned, including ship editing and randomly generated enemies. I talk about it in my Katamari Mech Spacey Devlogs if you're interested in learning more about my process.
