What is Touhou Defense Tale ~ AI Test in Touhou ~?
If you're into Touhou or just bored of the same old TD loop, you've gotta try this. It's a chaotic mashup of tower merging and bullet-hell action that turns a static genre into something way more active.
Gameplay
You aren't just placing towers and watching them work here. It's a wild mix of tower defense, merging, and RTS-style controls that keeps you moving. You'll spend your time summoning Touhou characters and merging them on the fly to build stronger units. It feels way more active than something like Defense Grid because you're constantly shuffling units to optimize your line. It's basically a bullet-hell TD, so expect the screen to fill up with absolute chaos fast.
The merge loop is the real hook. It's got that rogue-lite 'just one more try' energy that makes it hard to put down. You'll keep pushing to see how fast you can clear stages to climb the leaderboard. However, it's a fan game and it shows. The UI isn't polished, and the balancing feels off once you hit the later waves. It lacks the surgical precision of Kingdom Rush, but the sheer energy carries it through.
Since it's free to play, the rough edges are easier to swallow. You're getting a fast-paced, anime-infused experience without spending a dime. Just don't go in expecting a AAA production; it's an indie project that knows exactly what it wants to be, even if it trips over its own feet occasionally.

Verdict
“Please add more characters it's so much fun.”
It's a solid 7/10. Grab it if you love Touhou or want a free, high-energy challenge, but skip it if you can't stand unpolished UIs and wonky AI.
