(This is a review of the original sprite series by the way)
First of all, this is the kind of series you have to take with a grain of salt and with quite a bit of Narm. TTA was essentially a fanfiction made long before Niosi fully established himself in the world of flash. The first 30 parts aren't very good and the series takes awhile to settle, but although the series is hit or miss as a whole, I feel as if you can enjoy it so long as you don't take it too seriously. The series does have some flashes of greatness and plenty of lampshading. It's not a groundbreaking series, and draws some very clear inspiration from .hack and most of the action is pretty much taken straight from megaman.exe. But if you look at it with a clean, open mind, TTA can make for an enjoyable series that, while it is obvious that it was made by a rather young Kirbopher before he honed his flash skills, it can make for an okay time killer, despite containing some cliches and obvious attempts at anime. Just dont compare it to his other work.
