The gravity gun is lovely. A purple and black cannon in the foreground, well modelled, with that sci-fi claw look. It gives the game personality straight away. The textured 3D planets against the black star field look good too, and the scale works, you feel small next to them. "First person 2048 in space" is a creative pitch and pushing celestial bodies together is a satisfying fantasy.
Nice touches: a master volume control in the menu before you start (plenty of people forget that), and the Game Over screen showing Score and Best Score, which is the basic thing done right.
My problem: I died within seconds, twice, on 0 points. The HP bar in the bottom left starts draining by itself and empties fast, and there's a TEMP bar next to it. I never worked out what was killing me. Proximity to the planets? Heat? Just time? There's no explanation anywhere inside the game, the controls only exist on the itch page, and what drains your health isn't stated at all.
One line on screen would fix the whole thing. Also, START SURVIVAL only responded to a double click, and the build title is still "relaxing fps", which made me laugh given how not relaxing it was. Good idea and a good looking weapon, it just needs to tell me the survival rule.
