This has some onloading problems.

To get into a fight you have to ignore the whole giant map and click the little red rectangle on the far right--fair enough--but then It seems like most of the buttons don't work?

You click next and advance and auto-advance and auto-descend and retry a thousand times and nothing happens. Finally you set the text box to 1 and enemies show up, but changing the number again doesn't seem to advance the waves, so you're just watching the starter tower one-shot waves over and over for, sure you can buy upgrades now but...why?

Seems like there's supposed to be a lot of content and complexity, but I don't have enough faith in the start to really dig in.
