• The options button did nothing
• I played on my laptop and had problems with anti ghosting when I tried to press left + up + space, though I guess the final game may have key remapping anyway (I prefer z for shoot)
• My console was spammed with "not multiplayer" every frame
• Destroying the asteroids early on felt tedious as it took a while and didn't have much challenge other than sit back and fire at them
• After splitting a meteorite once with the laser, I wasn't able to use it again. I'm not sure if that's intended but there was no indication of why I couldn't use it.
• It's not clear that an asteroid falling into a sun is a lose condition.

I played twice and lost both times on the pair of asteroids after the laser. Top-down space things can be fun, but I wasn't feeling it so I didn't try again.
