Despite rolling out a playable concept demo for fast-paced scrolling shooter Humans Must Answer (you know, the one with vengeful space chickens), ex-STALKER devs Sumom Games still haven't managed to raise the modest $5000 to Kickstart the project. With only six days remaining, they've added a £7 reward tier that grants backers a discounted copy of Humans Must Answer along with Syder Arcade and Rhythm Destruction. I can't vouch for the latter, but Syder Arcade is seriously good fun.
So, basically, go download that demo and check it out for yourself. If you like it, you could probably do a lot worse for £7.
