Pro Tips
- *Use short sprints: 15 minutes to get a click working, 15 minutes to add one idle feature, then 15 minutes for a visible upgrade. Mixed abilities can all show progress in a single class.
- *Tie upgrades to standards: ask students to justify an upgrade with a formula, data source, or scientific principle, then display the math in a tooltip or info panel.
- *Require a save system early using localStorage so students can iterate over multiple days and practice state modeling like objects and arrays.
- *Introduce balancing last: once mechanics work, have students graph inputs vs. outputs and tweak coefficients to avoid runaway growth or player stalls.
- *Run a showcase with remix rules: students must fork a peer project, add one mechanic and one graph, and write a 3-sentence changelog explaining the impact.
