Simple, well made game! I included it in my compilation video series of all of the GBJam 5 games, if you'd like to take a look :)

This game just doesn't become challenging. It needs to get faster as time goes on or different enemy types should show up.

Simple and fun! With a sound track and more variation (different enemies? weapons) this game can quickly become more challenging and even more appealing. Using the cannon is really satisfying! ;)

Simple but addicting yet game. I'd try to add some variation to keep interest after a few minutes of play, but it's a good start.

Simple but funny game.

It needs some more progression. Good work anyway!

Very simple but works fine, could need more progression and music

It's a very basic game. If you just added a little bit of progression it'd be a lot better, for example as time goes on there could be more/faster asteroids. As it is I don't think there was any progression and it didn't seem to be going anywhere and I couldn't lose. Otherwise pretty solid jam game. Played web version.
