First Installment Wins: The arcade version is the most well known, partly due to its other games not being ported as much or, in Mappy Arrangement's case, at all.
More Popular Spin-Off: The arcade game was based on a series of maze-solving robot toys that Namco created back when it was in the robotics industry. These days, the toys are much more obscure than the game and its spin-offs.
The original game is one of Namco's more challenging arcade games, for a variety of reasons. Among them is that Mappy has no direct way of attacking save for opening certain doors, the trampolines vanish if you use them too much (leaving a bottomless pit in their wake which, if you're unlucky enough to use all the ones on the bottom, will make a level impossible to complete) and the cats can easily corner you if you aren't being careful.
Arrangement is no slouch when it comes to difficulty either, with it adding a fifth Meowky and tough boss fights that require tons of skill and strategy if you want to beat them without dying (which you will want to do; you've got at most 4 lives to clear 26 stages, and don't even think about continuing if you value your score). If you want those end-game point bonuses, you've got your work cut out for you, especially for the million-point Pairing Bonus, which requires you grabbing two of each item in a specific ordernote Two radios, two televisions, two computers, two paintings, two safes in every stage.
ShiftyLook Series:
Broken Base: When the episode first dropped, the finale was rather contentious to some. Some fans believe it to be a perfect send-off to have Goro and Mappy accept the fact that they're eternal rivals, whereas others find the ending to be too depressing because of Mappy being vilified for getting Nyamco shut down despite doing the right thing in getting Goro arrested, as well as ending with Mappy and Dig Dug getting arrested due to Mappy attempting to correct his "mistake". As a result, some fans prefer to consider Episode 12 to be the real finale. This has generally become less common of an opinion among modern viewers (see Cult Classic below), with more people finding it particularly funny and joking about Mappy destroying capitalism instead.
Cult Classic: Hit a small but loyal fanbase in the early 2020s, almost a full decade after the series had concluded.
Foe Yay Shipping: Goro shows some questionable behavior towards in Mappy in several episodes of the web series. Fans are keen to capitalize on this.
is very catchy.
