Fun concept but yeah as others say I basically never ended up using the spin after I had a few turrets and once I got the laser turrets I had enough money to just fill every slot except for 1 shield and was basically unkillable.
Maybe having a variety of weapons that work on different things coming at you so you need to spin to use the right tool?
Repairs were also basically free so I was just spamming it any time something took a bit of damage and a repair all or hotkey for it would be good if you want repairs to be frequent.
Overall I had a fun time going through all the upgrades and beaming the asteroids and ships was pretty satisfying!
