Your best move
might be theirs.
Race another team up a 336-metre tower. Reach the summit or outlast the rival jumper. First team to win three rounds takes the match.
See the next landing.
Place springs where your partner needs them, manage your charges, and adapt as the race changes. Every spring is public. Build smart: the other team can steal your boost.

FROM DOWNLOAD TO FIRST JUMP
Get in.
Get airborne.
Try Learn to Fly first, or choose Play → your role → Practice with Bots. Empty roles are filled by bots.
01 Android
Download the APK to your phone and open it. Android may ask you to allow installation from your browser or file manager. Install the game, then open Nattat.
This is a direct-install test build, not a Google Play release. Android 8 or newer with ARM64 support is required. Physical-device performance is still being tested.
02 Windows
Download the ZIP, choose Extract All, and open Nattat.exe inside the extracted folder. Keep the files together.
The test build is not code-signed; Windows may show an unknown-publisher notice. No Docker or additional game launcher is needed for practice.
A FEW BUTTONS. A LOT OF POSSIBILITIES.
Learn the moves.
On your phone
Jumper: touch the movement side and slide to steer. Hold JUMP to chain jumps. Tap BURST, or drag and release it to aim.
Builder: drag to aim your spring, then tap PLACE. Use SHATTER to remove your unused spring.
Options includes control size, reach, left-handed layout, sensitivity, optional tilt, sound and gentle effects.
On your keyboard
Jumper: A / D or arrow keys to move. Space to jump; hold to chain. Shift + direction to burst.
Builder: mouse to aim. Left-click / E to place. Right-click / Q to shatter.
Build horizontal speed before jumping. Combo counts celebrate linked climbs; your run-up supplies the jump power.
BRING YOUR TEAM
Same Wi-Fi.
Shared chaos.
Up to four players can join a local match across Windows and Android. Everyone needs version 0.4.1 and a network that lets devices communicate.
Internet matchmaking is not live.
Online party-code hosting is still in preparation. For this test, use HOST LAN / JOIN LAN. Leave the playtest service and access-key fields empty.
- 1
One player hosts.
On a PC, go to Play → Play with Friends → Connection Settings and choose HOST LAN. Allow Nattat on your private network if Windows Firewall asks.
- 2
Friends join the PC's address.
On the host PC, open Command Prompt and run
ipconfig. Find the Wi-Fi adapter's IPv4 address. Other players enter that address in the bottom LAN field, then choose JOIN LAN.127.0.0.1means your own device—it will not connect a phone to the host. - 3
Pick roles. Ready up. Fly.
Choose Jade or Coral and an open role. Everyone presses I'M READY. The party leader presses LET'S FLY. Keep the host's game running.
Trouble joining a local match?
Check that everyone has 0.4.1, the host is still running and the address matches its current network. Avoid guest Wi-Fi: it often isolates devices. The host firewall must allow the game on the private network (UDP 7777). Disconnect a VPN if it changes local routing. The LAN lobby may show a leftover “share this code” instruction; use the host's address instead.
YOU'RE EARLY. THAT'S THE POINT.
Help shape
the next climb.
Play a few rounds. Try both roles. Tell us what made you grin—and what got in your way.
01 Did movement feel responsive?
02 Did the longer climb hold your attention?
03 Was building as fun as jumping?
04 What would make you play again?
Include your device, game version, role and solo/LAN mode. GitHub issues are public; leave out personal information. No GitHub account? Email works too.
What is collected during the playtest?
The game has no accounts or automatic analytics uploads. Playtest Notes can save an optional report locally; you decide whether to share it. Sending email or opening an issue shares that feedback with Korionx Productions through the service you choose. This page adds no analytics trackers or feedback database.
