I'm in a bit of a hurry here, so I haven't got long enough to go into detail about how No Time To Explain is the hot new indie platformer, you're just going to have to look at the pretty moving pictures contained within this launch trailer:
Aside from featuring fights with big flying saucers and weird shark-squid things, No Time To Explain has a level editor (with about 200 user levels submitted during the beta alone), and will be getting a free update, adding a second episode, in December.
Cost of entry is $10 USD, and it's available to buy from tinybuild.com right now, and they will be submitting it to "Steam and other distributors" within the next week.
The original Flash version is still available here, if you want to get a taste of how it plays. Hopefully they'll put out a proper demo too.
