The reason? Steam, I've found out by handling Deus Ex Machina 2, is an invaluable platform for getting your games in the public eye.
To get one of your games on Steam it needs to go through a submission process, Steam Greenlight. Games players vote on whether they'd like to see your game available on Steam.
I'd been wondering about submitting Slightly Magic to Steam, but to be honest thought it might be too retro to catch the imagination of today's players. Anyhow, a couple of recent heart warming emails persuaded me to give it a go.
If you've a Steam account you can vote for Slightly here. Of course, every 'no' vote is a knife through my heart, which is why 'putting myself out there' is a little stressful. Ah, well.
