A good choice in inspiration when creating such a game. Right, left and shoot - enough actions to shuffle the keys. It was very nice to get used to the new controls, perceiving the keys in a new way.
A bit of technical feedback: It would be cool if shots flew through the explosions into the next ships, rather than being destroyed. There is no feedback on damage from healthier ships that are not destroyed by a single shot, but I hope this is temporary.
Good polished game!
UPD: Forgot to mention, I had one time when my controls mixed up and nothing changed. So, an extra check of the new control scheme with the old one would not hurt here.
