AI Analysis
●●●BangerWizardryZero to OneNiche Gem
Celeste playable on a $15 microcontroller as a 42kB ELF binary.
Strengths
- •Genuinely inventive constraint: fitting a full platformer into ESP32 memory and display limits.
- •Novel packaging approach using custom ELF installer eliminates traditional firmware flashing.
- •Playable, not just a proof-of-concept—son completed the game on hardware.
Weaknesses
- •Niche audience: only appeals to embedded systems tinkerers already invested in ESP32.
- •YouTube-only documentation; no GitHub repo link visible for others to build/modify.
