Drag to aim, release a volley of glowing balls, and crack through numbered strata. Draft perks every 15 depths. Get crushed and the run ends.
- Aim-and-release volleys with ricochet physics
- Perk drafts every 15 depths — Volley, Power Core, Blast Radius, Chain Reaction
- Run persistence with CONTINUE, hit-stop juice, and no forced ads
Ionstorm
A horde-survival roguelite. One thumb, hundreds of enemies, and a boss that keeps coming back stronger.
Touch anywhere to move; your weapons fire themselves. Build your loadout one level-up at a time and face The Collapsar at 6:00 — then again, harder, every 2.5 minutes.
- One-thumb control — weapons fire themselves
- Five weapons, dozens of upgrades, build a loadout per run
- Escalating boss waves and a readability-first visual language
Massward

Glide around a living arena, absorb smaller cells to grow, dodge the bigger ones, split to catch prey or escape, and steer clear of the viruses.
- Grow-by-eating arena movement
- Split mechanics for catching prey and escaping danger
- Single-player — no servers, no lag, no forced ads
Orbitfall
Gravity-slingshot golf — the calm, premium skill-puzzle of the family. Bend your shot around the wells and find the wormhole.
Pull back to aim a probe, watch the prediction arc bend live around gravity wells, and release. Fewer flicks means more stars. Every sector is machine-proven solvable.
- Pull-back aiming with a live, bending prediction arc
- Star ratings by flick count — one flick is three stars
- Seed-fixed endless campaign — everyone flies the same sectors
Starward
A gravity-well orb-merge arcade puzzle. Fling, merge, chain — and detonate a supernova when two quasars meet.
Orbit the launcher around the well and fire glowing orbs. Matching tiers merge upward — DUST to QUASAR — and fast chains multiply your score. Let an orb loiter too long and it's over.
- Orbit-and-fire launcher control
- Nine merge tiers from DUST to QUASAR with chain multipliers
- Supernova detonations and a 2-second loiter loss condition
Sumward
A number-synergy roguelite deckbuilder — Balatro's chassis with the portfolio's arithmetic DNA.

- Draft number cards and build a synergy deck
- Pattern-scoring hands: pairs, runs, sum-to-ten, prime sets
- Relics, enhancements, and an Exchange shop between rounds
Tunnelrun
An endless tunnel dodger — pure reflex arcade. Weave through gates as the speed climbs and the tunnel tightens.
Drag to weave through gates flying at you — holes, blocked sectors, spinning bars — while speed climbs from 320 to 900. Emerald shields absorb a hit. Near-misses score. Distance is the run.
- Relative-drag steering — your finger never covers the ship
- Escalating speed and three gate types to weave
- Emerald shields, near-miss scoring, and provably fair gates
Ward
A defense without guns. Drag gravity wells to bend every attacker into the sun — you never fire a shot.
Enemies fall toward your core from every direction. Place up to five gravity wells, bend each attacker's path into the sun or a crush radius, draft perks between waves, and hold the line.

- Live, color-coded trajectory prediction at 10 Hz
- Roguelite perk drafts and persistent runs
