Download DELTARUNE for macOS

Chapters 1–5 are now bundled together, so you can play straight through Toby Fox's parallel story without waiting for the next drop.

ARM-native RPG from UNDERTALE’s creator

• Episodic RPG from the creator of UNDERTALE
• Native ARM and x64 build
• Tested on macOS Sequoia with an M4 chip

Steady frames and snappy timing on M4

It's a native app, not a port wrapped in emulation. On an M4 Mac mini it holds a steady frame rate with barely a whisper from the fan. Keyboard controls feel snappy — the timing-based combat lands the same way it does on Windows. You can use a controller too, but the arrow keys and Enter are all you really need.

Let’s say you missed UNDERTALE back in 2015. Your Steam library is full of action-heavy titles, and you’re after something that won’t punish you for an evening of low-energy gaming. You download DELTARUNE on a whim, and within twenty minutes you’re dodging chalk in a classroom brawl, grinning at the absurdity of it. The writing gives you that rare feeling where you’re not skipping dialogue — you’re leaning in. For someone who plays on a MacBook Air while sprawled on the couch, the low system demand means the bottom stays cool and the battery barely notices.

A mini-session with Chapter 2

You boot the game around 9pm, headphones on. The disk image took seconds to mount earlier, and the app already lives in your Applications folder. Tonight is about exploring the Cyber World.

1. Tap Enter to skip the intro cutscene — you’ve seen it twice already while showing the game to friends.
2. Kris wakes up in bed. You steer them downstairs with the arrow keys, muscle memory kicking in. The town theme hums along, gentle enough that you pause to just listen for a moment.
3. Susie joins the party. You head into the dark world and the palette shifts to neon blues and purples. Enemies pop up on the overworld — you nudge Kris into one to start a fight.
4. Combat begins. You hit Z to confirm a FIGHT command, then time the slash to the beat. No grinding necessary — you’re here for the dialogue, so on the next encounter you choose ACT and SPARE a plug-boy who just wanted a hug.
5. Twenty minutes in, you hit a puzzle with moving platforms. You hold Shift to walk slowly — easier to line up the jumps. The solution clicks after two tries.
6. You save at a sparkle point and call it a night. Full shutdown takes two seconds; tomorrow you’ll pick up exactly where you left off.

Quieter touches worth knowing

Plenty of small details sit just outside the main path. Here are a few that make replays feel different from a first run.

• Hold X to walk instead of run. It’s not just for puzzles — characters sometimes react when you approach them slowly, and it stops you from skidding past doorways in tight hallways.
• The spare mechanic isn’t binary. Wearing down an enemy with complementary ACT options can unlock unique dialogue, and some battles resolve without a single FIGHT command if you’re paying attention to their body language.
• Dialogue logs don’t exist, but pressing C during a conversation opens a handy recent-text bubble so you can re-read the last few lines if you clicked through too fast.
• The game auto-saves frequently, yet manual saving at sparkle points also restores your HP — a quiet way to top off health without using items.
• Sound design cues often telegraph attacks before the visual tells appear. Playing with headphones isn’t just immersive; it gives you a split-second advantage during tougher bullet-hell patterns.

• Chapters 1–5 are all available in one download.
