SuperTed

SuperTed is an action game that was developed by Longman Software for the Sinclair ZX Spectrum in 1984; it is based on that Siriol Animation and S4C television series of the same name (specifically, the 1983 episode "SuperTed at Creepy Castle"), and the player must use either the 5, 6, 7, 8 keys or one of various types of joystick to direct SuperTed around the Creepy Castle, which has nine rooms, capture Texas Pete, Skeleton, and Bulk, then imprison them before the bomb on the right side of the screen explodes, and takes Creepy Castle with it (however, this didn't happen in the actual episode).

The two squares at the top-left and top-right of the screen indicate who is in which room of the castle at any time - SuperTed himself with a red square when magically charged and a yellow one when he isn't, Texas Pete with a cyan one, Skeleton with a gray one and Bulk with a magenta one. In order to capture any villain SuperTed must walk up to him (while magically charged) and then take him to the castle jail; the text "At large" at the top of the screen indicates which villains are still at large while "In jail:" at its bottom indicates which ones are currently in jail. If SuperTed walks into one of the flashing yellow objects which are placed around the rooms he'll lose his magic powers - and without them, he can't capture the villains, or take them to the castle's jail, so you shall have to direct him to one of the red blancmanges, that are also placed around the rooms, in order to recharge him. Also, if SuperTed should take too long, over imprisoning all three villains, any of them who have been imprisoned shall escape and have to be captured again; this will almost certainly seal your doom if you're low on time.
