Drag up and release: your heroine casts a volley of mana orbs that bounce off the walls and the wakelings. Every hit releases mana as a number, and each further hit by the same orb is bigger. Released mana flies on and hits the next wakeling. Colliding numbers merge in your heroine’s way; at 50 the mana overflows and calms the wakelings around it. Three overflows charge the heroine’s flourish, which doubles every number on the board.

Each heroine merges mana in her own way. Shiori adds colliding numbers. Harin multiplies numbers up to 9 and adds bigger ones. Lian adds them with one extra stroke, and her prime numbers hit a second wakeling. Rika’s powers of two double on every bounce. Shiori and Harin are in the free game; Lian and Rika come with the full version.

After waves 3, 6, 9 and 12 you pick one of three paper talismans that change the night: for example an extra orb, springy walls or a lower overflow threshold. Some can be taken several times.

Every wakeling that reaches the town gate puts out one of the three lanterns there. Aim so the orbs bounce between wakelings rather than straight past them, save the flourish for a crowded board and pick talismans that suit your heroine.

Yes. The free game has Shiori, Harin and the meadow, the whole first chapter. One in-app purchase unlocks the full game: Lian and Rika, the crystal mine, the night forest with the finale and the rest of the gallery. There are no ads, lucky draws or subscriptions.

Yes, partly. The illustrations, sprites, sounds and music are made with the help of AI models. A person at Wumiko picks and edits every file before it goes into the game, and the world, characters and rules are our own.

Overmana is in testing and will come to Google Play and the App Store. Testers are invited by us; there are no store links yet.
