スペルトナエル

*Caution! Localization to English has not yet been started. *

Race across the letter board, complete spells, and fight.

Will you finish casting amid a storm of bullets, or build something powerful enough to break the entire game?

A brutally challenging action deck-building roguelike.

↑Survive the cycle of day and night and make it all the way to Day 20.

Fall along the way, and this roguelike sends you straight back to Day 1.

Despite how it may look, this is a seriously challenging game that demands quick decision-making, action skills, and strong overall game sense.

Players who love experimenting until they find a build that completely breaks the game

Players who enjoy brutally difficult games that keep their brains working at full speed

Players who enjoy testing and gradually understanding the rules of a world

Players who can laugh even when the odds are overwhelmingly against them

Players looking for a dense, satisfying experience in runs of around 30 minutes

This is a game that people tend to either love or hate.

It is not designed to explain everything from the beginning.

You are expected to fail repeatedly and gradually learn how the game works.

It is also a hectic real-time game that constantly demands both movement and decision-making.

👉 If you value immediate, intuitive thrills more than trial and error, this game may not be for you.

Race across the letter board and chant the letters of your spells.

Once every letter has been chanted and the spell is complete, its magic activates.

↑Move across the letters “P,”"A," “N,” "C," and “H” to cast the spell “PUNCH” and attack the enemy.

Strategy matters: you must decide which spells to cast and in what order.

Enemies will not wait patiently for you to finish casting. They constantly try to interrupt you with barrages of projectiles.

↑The flames are enemy projectiles.

You take damage when they hit the heart-shaped cursor.

Without enough stat upgrades, a single hit may be enough to kill you...

The key to combat is continuing to cast while weaving through the bullet patterns.

But do not worry if bullet hell is not your specialty!

↑Raise your defense high enough and you can become invincible.

↑Animals are dependable allies that erase enemy projectiles. They do get in the way a little, though.

At night, you can buy and sell spells at the shop.

Short spells are weaker, but you can cast many of them quickly.

Long spells are powerful, but take more time to complete.

It is also important to choose combinations of spells that can be chanted efficiently at the same time.

You may find yourself staring very intently at the letter board...

What kinds of spells are there?

A spell that summons an invincible dog. The more often you use it, the larger the dog grows.

A spell that massively increases every stat—but kills you three seconds later.

A spell that increases your monetary rewards in exchange for attracting every enemy projectile toward you.

How you use them is entirely up to you. You are free to exploit them, too.

Follow Two, a reclusive girl who sets out on a journey with a magical book.

Here, you are free to do almost anything.

As long as you have enough time and money, you may cast whichever spells you like, as many times as you like.

You are free to break the game. You are also free to become frustrated and give up.

↑You can obtain enough overwhelming firepower to obliterate every enemy.

↑You can summon an impenetrable wall of animals that blocks every projectile.

↑You can even construct a completely uncontrollable, fully automated spell-casting system.

Are you ready to dive into 20 days of letters and spells?
