I played this game on my stream (VOD) and you were there :)
Overall, this game is hard! I watched Hythrain play it and he made it look easy haha. I don't think I would have gotten far if not for the ghost potato being invulnerable :D
I really liked that there was a ghost potato that was invulnerable. It was a lot of fun killing the enemy ships that way.
The 3rd ship I tried, the one with rotating shields, was pretty fun to play too! I didn't notice that the outer shields would eventually get depleted though, so maybe changing the visual there a bit might help?
Fun game!
