Aim of the game
Repeadetly Press / hold A button to move the worm around, dont hit obstacles and walls, try to gain highest score.
High Scores
High Scores are only saved for levels 1 to 99 per game mode. If you select rnd2 levels, it will also select levels randomly higher than 99 but those all share a common highscore. If you want to compete with friends select a level manually to compare scores.
Seed System
The game has a seed system, you can choose a number between 1 and 99 for the seed. Selecting Rnd1 will select random levels between 1 and 99 on every (re)start, where highscore is saved for them. Rnd2 will also select random levels higher than 99 but it will use a common highscore for these levels. This is similar to how it was initially implemented in the previous version. It allows you to play random levels different from the fixed 99 ones.

History
V1.2
- Fixed 99 levels so people can play same levels
- RND1 (random level between level 1 & 99)
- RND2 (random level but higher than 99 also this is how version 1.0 worked)
- Highscores for first 99 levels per game mode
- global, shared highscore for levels > 99, this is how version 1.0 worked
- Fixed tunnel gaps appearing, removed addition of tunnelspeed when creating new tunnelsections, all tunnel sections adhere to tunnelsectionwidth
- UP/DOWN increases / Decreases level by 1
- L/R increases / decreases level by 10
- Better collision checking, it now checks also on intersections instead of player being fully inside somewhere (like a wall, obstacle, or collectable)
- Obstaclewidth increased from 10 to 12 to make sure we can’t fly through it
- Speed optimazations (not that they were required)
- Renamed “Seed” to “Lvl” to make it more clear
- Can increase game mode by left clicking on score as well (handy for phones)
V1.1
- Fixed bug where using same seed and same game mode on different platforms did not produce same levels
- Added Fullscreen switching with F or ALT + ENTER
- Added code to prevent accidental (re)starts of a game
- Web version will now scale to document size, making it able to run fullscreen as well as on different mobile phones
- Added macos-26 build
- Added macos-15-intel build
