Time Pilot (and TP 84 are both high up on my list of arcade greats). I've always hoped someone might take a stab at making more levels for Mr. Do (another Z80 game). The existing arcade levels have paths carved out in the background of zero through 9. What if there were additional levels using A through Z as the pattern? Just a thought. Or maybe a level editor and the end user could make and save levels and post them online for others. Nothing complex mind you. I'm thinking of an even simpler editor than Lode Runner. Again, great work and awesome attention to detail. The tightness of control in Ms. Pac-Man Amiga is the best I've seen. Perfect for twitch players.
