M5StickC Plus2 - Neon Genesis Evangelion Tamagotchi

What started as "I wonder if a Tamagotchi could run on an M5StickC" turned into a full NERV terminal with 9 mini-games, 12 Angels, real-time stat decay, CRT glitch rendering, and deep sleep persistence.

No poop mechanic. EVA doesn't do that.

The idea

The M5StickC Plus2 is the right size to look like a NERV terminal if you squint. The Tamagotchi format maps perfectly onto Evangelion — a creature you need to feed, fight, and keep from losing its mind. The sync rate is happiness. Rage is what happens when you ignore it. Core Breach is death.

The aesthetic follows the series: dark backgrounds, green phosphor text, uppercase everything, scanline overlays. Nothing friendly.

What it does

Four stats. Six actions. Twelve Angels.

FEED — six NGE-themed foods with distinct stat profiles. SOUL FRUIT boosts sync and lowers rage simultaneously. EMERGENCY BAR tastes like existential dread.

FIGHT — 9 mini-games selectable from a menu. Each shows two lines of instructions before it starts. Angels trigger specific games based on what they do in the series — IRUEL sends you into the MAGI voting system, ISRAFEL makes you mirror a sequence, ZERUEL demands everything you have left.

MIND — psychological recovery session. Three random modes: interactive NGE quote with two interpretive responses, guided breathing, or AT Field meditation. Costs almost no energy.

REST — sleep mode. Display dims. Stars appear. Energy recovers.

DATA — pilot file, stat readout, NERV logs, 25 canonical quotes from the series.

SYS — change unit, toggle sound, standby with clean shutdown, system reset.
