About this game

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.

Unfolding World

With each loop, you gain access to an expanding web of actions. Your goals and strategies will constantly evolve as you prepare for the ultimate fight. As you delve deeper into the system, the number of available actions scales to over 300.

Visualize the Math

As an idle game, the math takes center stage. Every formula is fully exposed so you can see exactly how to respond to it. A scrollable map with multiple zoom levels lets you step back and visualize the exact state of your complex network at a high level.

Route the Flows

Your primary resource — Momentum — generates and increases automatically. Your core gameplay loop involves routing it in different directions based on your current objectives, whether that's boosting Momentum generation or unlocking new action nodes. With multiple secondary resources in play, choosing the correct directional flow is the ultimate optimization puzzle.

True Idle Game

Designed to be played over weeks and months, this is a true idle game. You will frequently set up your flow logic and then step away to let the harvest play out, with new unlocks and hints keeping you engaged for the long haul. To ensure your time is respected, being offline or paused banks Bonus Time at 100% efficiency. You can spend this to multiply the game's simulation speed, ensuring no time is ever wasted.

Design Granular Automation

As you play, you will unlock deep automation tools. These give you the ability to dictate exactly when and by how much your downstream flow dials shift, enabling complex decision-making tailored to your current stats and situation.

Prestige and Time Compression

After a few hours of build-up, you can engage the Lich's Forces. This resets your current progress and pushes you as far as your build allows, rewarding you with resources to spend on a massive upgrade tree. The core strategy lies in selecting the most efficient upgrades to compress the timeline of your next run, allowing you to reach new heights faster!

Prestige, Second Order Reset, and New Game+

To keep the progression and time compression flowing endlessly, the game features two distinct layers of prestige restarts, as well as a New Game+ with its own upgrades, for players who want a little more! Each reset layer is curated to continuously evolve the player experience.
