I gave this a couple of tries, it's actually quite challenging to get as many companions as possible, while bumping into as few walls as possible and not running out of time in the end. But I managed to beat the first boss and reach the second.
I really like the idea and the way you embrace the 0 gravity movement. It not only gets you around, but you also use it to defeat the alien kings. And bumping into them and smash them into a wall feels really satisfying. The gameplay is simple, but engaging.
The alien companions (and the spritework in general) look really cute and are well made. And the dying animation of the first boss kinda terrified me at first xD.
The lack of music is a shame, but it is a Game Jam after all. Things sometimes don't get finished completely. Let's just say the game's realistic because there's no sound in space lol.
A couple of nice details I noticed: The inclusion of a pause screen and a tutorial is always a nice. And actually moving around on the menu is actually super cool.
I honestly had a good time with it. It was difficult, but worth to push through, just for the gruesome boss dying animation alone :D
