Hello!
I recently took part in a game jam, where journalists and developers swapped roles for the weekend. I was paired up with a student developer and had to make a game in 48 hours. We made a shmup called
Just Like Real Life.
You can play it
here, you'll need to have the unity web plugin installed. There will be a downloadable Windows/Mac version available shortly.
It's designed around mouse control, so that's what you'll need to use. We only tested it on 16:9, not sure what it'll do at other resolutions.
It's not a massively polished game, it was made in a bit of a hurry, but hopefully you might find it fun anyway.
It features a generative discordant soundtrack, procedurally generated levels and an online leaderboard.

Develop has all the coverage of it.

The video kindof reminded me of Galaga Legions on XBLA, but gameplay turns out to be quite different. And it's insanely difficult!
