Mercywave
A princess in a dark world shoots kindness — healing enemies at the cost of her own Light.
Light = ammo = life. A healed enemy sends out a Wave of Mercy and goes on to heal others — a cascade is born. The game world is the inner world of Aurora the ballerina, and dark damage is suppressed feelings.

Vitaly WeberVisionary·DesignGDD v1.4MercywaveOnboarding and economy
Playtests showed newcomers couldn't clear even level one. Added a 5-level progression (one enemy/type at a time), removed the passive tick, added per-level damage ramping, and made L5 a real wall. The simulator confirmed the curve.

Monte-Carlo Light-economy sim
Built a Light-economy simulator (~4000 runs per config) — data instead of feelings. Diagnosis: the core was too forgiving. Added a “challenge pack” and replaced the confusing passive drain with “corruption drains Light”, with clear telegraphs.

Detailed balance
A big balance table: enemy stats, Light economy, cascade thresholds. The key fix — Light is now spent only on hit (cost-on-hit), not on misses. Reworked “Denial” from a dead end into a positional threat.

The roguelike challenge problem
Admitted it: the mechanic is great, but the challenge failed — the healing cascade is positive feedback that drains tension. Introduced “4 pillars of difficulty” to bring the pressure back.

Narrative and the switch to top-down
A narrative flip: dark damage is suppressing feelings, healing is acceptance. The heroine is Aurora, a ballerina; the game world is her inner world. Switched to a 2D top-down twin-stick roguelite so the healing cascade reads from above, and built a graybox prototype.

Start: genre and concept
Analyzed a SteamDB dump to pick a solo-viable genre, and the core idea was born: a princess who “shoots kindness” — healing enemies at the cost of her own Light. Light = ammo = life. GDD started.
