Wow, really liked this, but you can only upgrade the first tower, which led to an error when I got it to level 7 or 8

Thanks! As for the towers, upgrade mechanics were the last thing I wrapped up with about 1 hr til deadline, so I finished the mechanic, but forgot to copy functionality to tower 2/3. I'll update the game on here once the jam wraps up with bug fixes and sound. Also, I forgot to hard limit the upgrades before submitting, so once upgrade reaches level 10, there is no more data in the tables to update atk/spd/cost, ect.
