Key benchmarks for first game prototype.
| Scope | Time | Team |
|---|---|---|
| Jam | 48 hr | 1-4 |
| Vertical slice | 2-4 wk | 1-3 |
| MVP | 2-3 mo | 2-5 |
Get the prototype in front of players before adding art or polish — fun must come first.
Commit after every working session — a broken build without a rollback point wastes hours.
Cut features aggressively for the first prototype — one polished mechanic beats five half-built ones.
Crucial code requirements, material risk alerts, and prevention checklists for First Game Prototype Guide.
⚠️ Risk Warning: Purchasing net calculated material causes project delays when cuts or breakage occur.
💡 Prevention Action: Always add a 10%-15% buffer allowance to initial calculated quantities.
⚠️ Risk Warning: Applying finishes to dusty or uneven surfaces reduces adhesion by up to 60%.
💡 Prevention Action: Vacuum, prime, and check levelness (max 1/8" gap over 10 ft) before starting.
