Gravity Courier is now available as a free browser playtest.

Play: https://mgkim2998.itch.io/gravity-courier-playtest

One small parcel. A room full of possibilities. Change gravity, put metal

weights on switches, cross portals and find a route to the receiver. A

clever shortcut counts, even if it is different from the solution I expected.

This first public test includes 10 main rooms and 2 optional challenges.

All rooms are available from the start, hints and checkpoints are included,

and returning after a successful delivery is optional.

It runs in a desktop browser with keyboard controls, with no download or

payment required. The game text is English; feedback in any language is welcome.

If you have 5-10 minutes, I'd love to hear which room you tried, where you

first hesitated, and which moment made you want to keep playing. You can

leave a short reply here or use the game page's comments. No need to

complete the whole selection.

I'm the creator and I'm using feedback to guide the next changes. Development

uses AI-assisted code and text, and some optional decorative backgrounds

are AI-generated. The attached clip shows actual gameplay from the test.

Thanks for trying it!

Room 1’s weight gates are a clean first verb. Tip for the next rooms: teach the gravity flip in a room that has almost no weights — if both verbs show up together, testers blame the wrong one when they stall. Ask “which room first made you stop and plan?” — a room number beats “it was fun.”
