Thanks for checking out my game! Glad you found the core mechanic somewhat engaging, I definitely could have done better in communicating their significance. Great point regarding the progress moving even when the laser is off. Perhaps a bit more visual indicators on the asteroid "heating" and persistent laser at "low" power could help create that link. I'll also do some rebalancing on the upgrades to improve the risk-reward ratio.
Really appreciate you sharing the things you liked as well. Gives me good insights on how to move forward, cheers!
