I played twice, got 68511 as a score - only just feel I'm learning the order to buy the upgrades. I think there might be a bug on the score, it seems it's not reset on a replay? (unless the score at the bottom is the high score)
Really cool idea, enjoyed it a lot. Great job. Could be something very addictive with a bit more juice (so hard to add juice on a tight deadline, my game is missing heaps of juice). Tightening up the fonts would be nice - as would pausing the timer during the shop activity (though that's a game design decision of course).
Edit: just wanted to say, love the Point Effector 2D (magnet) - I put them in all my games - see my GDTV 21+22 entries if you have a chance. I was sad to discover there isn't a Point Effector in 3D Unity.
Edit 2: played again, I like the new enemies, managed to max everything out with 2:18 left, got 333,001 total.
