Sans Simulator
Sans Simulator is a fan-made challenge based on the famous Sans fight from Undertale. You control a tiny heart (your SOUL) and try to survive waves of traps. The goal is simple: stay alive as patterns get faster and the KARMA effect keeps draining your HP after hits.
How It Plays 🎮
You dodge bones, lasers (Gaster Blasters), and platform traps inside small rooms. Some waves switch gravity or add moving platforms. The key rules are easy to learn but hard to master.
- Blue attacks: stop moving to avoid damage.
- Orange attacks: keep moving to avoid damage.
- KARMA: damage lingers and keeps draining HP for a moment.
- Patterns: each wave has a rhythm—memorize, then move early.
Modes & Options 🧩
- Full Fight: the classic sequence from start to finish.
- Practice: repeat one wave until you can clear it.
- Endless/Survival: random waves until you fall.
- Difficulty: Easy to Hard (names vary by version).
- Custom tweaks: HP, speed, or invincibility frames in some builds.
Controls & Interface 🕹️
Movement is precise and small inputs matter more than big swipes.
- Move: Arrow keys or WASD
- Confirm/Pause: Enter / Esc
- UI cues: watch bone colors, blaster charge lines, and screen borders
- Health bar: shows HP plus the purple KARMA drain
Tips For Beginners ✅
Start slow, learn the color rules first, and listen for audio cues. Treat each wave like a short puzzle: where is the safe path, and when should you move?
- Make micro-movements to slip between bones.
- Keep space around you; corners can trap you.
- If you get hit, reset your rhythm so KARMA doesn’t snowball.
- In Practice, aim for three clean clears in a row before moving on.
What To Expect 🌟
Runs are short, retries are instant, and improvement is quick but satisfying. It’s perfect for players who enjoy pattern learning, tight dodging, and a fair but tough test of focus.
