Alley is a user in Platform Builder forums that created some notable games such as Invasion: Going Personal.
Before his game at Explore, he started to search for information about Platform Builder when it even wasn't available for download. The first projects were some kind of remakes from other game which needed to be similar as much as possible with the originals which were all canceled because of an inability to decide how to plan the game visually. This was the beginning of the main project to Platform Builder that was no remake and which focused more on spending less time and doing more work. However, Alley always tried to include something more complicated that Platform Builder even didn't allow to make directly such as bosses when there was no direct feature for this. A goal for the latest project was to prove Platform Builder abilities to the community.
