About Time, Space and Matter
Resemblance
Some players might find a resemblance with Portal. However, unlike clones, TSM is an original game with original ideas and has, in fact, nothing to do with Portal, although it was a considerable influence.Features
- Logical 3D space navigation
- Both slow-paced progression and fast-paced action
- Freedom of approach in solving puzzles
- A lot of fun with gravity blasts
- Bonus content for completionists
Disclaimer
This game is no shovel-ware. It's development took over two years and was conceived by me in my spare time. Aside from selected songs and audio tracks, the game only contains original ideas and original assets.
