What is with all these youkai popping up everywhere—?!

“'幻想郷大激突: Touhou Impact' is a Touhou Project fangame and survival action game inspired by Vampire Survivors and Megabonk.”

About the Game

Youkai have appeared.
A lot of them have appeared.

No, far too many have appeared.
This is definitely an incident.

But there’s no need to worry.
The way things work in Gensokyo is always simple.

Beat them all up first, find the culprit later.

幻想郷大激突 : Touhou Impact is a casual bullet-hell survival roguelite where you roam 3D battlefields and wipe out endless hordes of youkai. Your attacks fire automatically, but it’s entirely up to you where to run, which experience orbs to collect, and what upgrades to choose.

You start with just one small attack.
But as you level up, lightning will chain between youkai, lasers will pierce through entire lines, auras will melt everything nearby, and projectiles will scatter in all directions.

At some point, you might start wondering if you’re resolving the Incident or making it worse!

The battlefield isn’t flat.
Climb hills, navigate the terrain, and find openings before the youkai surround you. The attacks handle themselves, but dodging is all on you.

Gather experience to level up and create your own style of youkai extermination with randomized upgrades.

With good luck, you’ll put together an awesome build.
Even with bad luck... well, you’ll still be firing a lot of bullets.
