Alight, Mr. NeonSpider, I think you're a dummy. You apparently didn't listen at all to the Delta tutorial in the tower, since you forgot you had a radius around this mysterious glowy orb thing at the end of the stage that is essentially a level editor. All you gotta do is take the orb back to the portal and delete the barrier around it. The only way I can see you failing to figure that out is if you never realized you could delete preexisting tiles in Delta mode, which the game doesn't outright teach you, but that's simple enough to figure out especially when you have to do it to pass through the stage after the tower. I really have no idea how you could get so stuck on this first stage.
As for my thoughts on it, it was pretty good for a 20143 Flash game. Maybe the combat mechanics could be more fleshed out and the Delta mechanic be used in more inventive and fast-paced ways, but it was alright. 4 stars, good effort.
