What the developers have to say:

Why Early Access?

“We want to use player feedback to help improve the quality of the game, find issues, and aid us in ensuring the game's balance has both depth and approachability.
In order to achieve this, rather than continuing development in a closed environment, we've decided that early access would be a faster route toward the goal of getting a wider variety of players to play our game.”

Approximately how long will this game be in Early Access?

“We estimate the game will be in early access for about 6 to 12 months.”

How is the full version planned to differ from the Early Access version?

“We're planning on the full version of the game having a wider variety of Items, Snacks (weapons), Spirit Strike Talismans, and events, as well as multiple new game mechanics, more difficulties to play on, a fourth chapter, and an achievement system, among other possibilities.”

What is the current state of the Early Access version?

“The early access version will allow you to play through three chapters, each consisting of multiple battle stages and a boss. There are eleven different difficulties available to play on, with the next difficulty being unlocked after winning a run on your highest available one.”

Will the game be priced differently during and after Early Access?

“It's possible we may change the game's price upon ending its early access period. However, we don't expect that we would raise it by much.”

How are you planning on involving the Community in your development process?

“We primarily plan on reading feedback posted to places such as the game's Steam discussions to find places that could use improvement, and then applying that feedback to help make a better game.”

About This Game

A strange yet succulent incident has begun... Gensokyo is overflowing with snacks! A roguelike twin-stick shooter Touhou Project fangame makes its debut on Steam!

Fight using the power of snacks!

Use your danmaku-firing snacks to mow down hordes of enemies. All the different snacks have different upsides and downsides, and will level up and grow stronger as you battle with them!
Rumia can also eat snacks to grow stronger permanently, additionally gaining that snack as a passive attack! Eat snacks to become stronger, but be careful not to overeat and get sleepy...!

Over 100 different items!

Once a battle ends, it's time to go shopping! There are a ton of different items to aid Rumia in her journey.
There are items that simply raise your stats, ones that summon battle partners that block bullets, and even ones that treat other items like you have two of them...!?
There's a whole variety pack of items to choose from, but don't forget to pick ones that synergize with your other items... and your snacks too, of course!

Turn the tables with talismans!

Spirit Strike Talismans can be used in battle and offer a wide range of helpful effects, such as dealing big damage and blasting away enemies, or buffing Rumia for a period of time.
Depending on your inventory of items, you might even find your battle tactics revolving around your talismans!

Will Gensokyo ever go "snack" to normal?

Snack Fountains have suddenly appeared around Gensokyo, and territory struggles have erupted around them... yet, nobody seems all that concerned!?
Entering an event space lets you take a look at how the other residents of Gensokyo are doing, and maybe even offer them some help! Maybe you'll figure out something about the ongoing incident, too?

The biscuits can get harder!?

Change the game's Biscuit Hardness to make things easier or harder! You'll unlock harder and harder difficulties as you keep winning runs.
But don't worry — you can always make things easier if you feel like the game is too difficult!
