Kill the Lich is a minimalist incremental game centered around time compression and resource propagation. Your resources build automatically over time, but their growth accelerates when you optimize their downstream flow ratios, and you can manually push them along to go even faster. Each action grants attributes that reduce the requirements of other actions, allowing you to push further. Eventually, you can head north to Fight the Lich's Forces in an automated Phase 2, gathering three vital resources that make your next loop faster and unlock new goals.
