A game that learns how you play
GRUDGE is an adaptive rage platformer. Instead of setting the same traps for everyone, it studies how you play and uses it against you. Here is what it watches, what it does with it, and why it stays fair.
What it watches
While you play, the game quietly counts a few simple things. Nothing personal, only how you move:
- Whether you tend to jump early or late.
- Whether you rush ahead or stop and look first.
- Whether you do what the signs tell you.
- How you die, and whether you die the same way twice.
What it does with it
Some later levels come in more than one version. The first time you reach one, the game picks the version built for your habits and locks it in. From then on that level never changes for you, so if you learn its trick, the trick stays learned.
The game also talks. It comments on how you play, and it does not sound the same at the end as it did at the start.
Your file
GRUDGE keeps a file on you. It sorts you into a play style (Reckless, Cautious, Methodical or Erratic), rates how predictable you are, and names the habit it has exploited most. You can open your file from the menu and share it with friends.
Come back another day and it remembers where you struggled last time.
Why it stays fair
Everything in the game is deterministic: the same moves always give the same result, down to the frame. Every jump it requires has been measured to leave a generous timing window, and every level has been checked to be beatable for every kind of player, whatever their habits.
It adapts between attempts and between levels, never in the middle of a jump. A path to the door always exists. You just have to find it.
Your privacy
Everything the game learns about you is stored in your own browser. There are no accounts. Only anonymous gameplay counts are sent, to see where players get stuck.
