After just like 4-5 rounds I have maxxed support, max attack speed and laser damage, which makes it very easy to get to 10 simultaneous laser. At this point I bought some defensive upgrades and could ignore the battle screen, buying mining upgrades rather mindlessly (also the mines' conveyors are too slow to take the output of all mines).

Besides that the girl's audio clip is repeating too much for my taste.

Overall I think this goes in a cool direction but you might want to change the balancing or expand on the gameplay so the max-out doesn't happen so early.

Thanks for the feedback.  A new version was just released with a second planet that is better balanced.  My first attempt at balancing was more a proof of concept for the game, to make it fun, but moving forward much more focus will be on balancing.  As for the packages moving slow, you can unlock a Package Speed upgrade now on the 2nd planet (and quotas are much lower).
