I successfully defended the tower! I wasn't sure I was going to make it. In fact, there are a lot of uninvited guests down there right now...
Nice, clean aesthetics and fun, straightforward gameplay. :) I very much appreciated the auto-fire! I also liked that I could 'plan ahead' a bit by firing off the appropriate number of fireballs toward a far off enemy before switching to a new lane. While, again, a pretty simple concept, it's still satisfying to feel clever in that way.
It's impressive you made this in ten days while also learning to use the program you made it in for the first time. Great job!
