When I decided to try Flixel for a variety of half a year or more ago and try to make my own platformer, I was initially surprised, and then I started to get angry at the lack of a normal tile editor. I have already played enough with the platformer and the flush, but having run into the beta I can not share with the habrasoobschestvom. A pair of rollers using under the cut. ')
PS The editor is written in Adobe AIR, so it works only under Win and Mac - it was not possible to launch under Ubuntu. If anyone can - bring it here. :(
PSS Bads has published a review of the Tiled Map Editor. I recommend to get acquainted.
