I'm surprised this game got overlooked even for the fact that pacman is on the main character's hat. Think of the gameplay like kirby 64 but with the ability to pick up and use enemies as either projectiles or to double jump. The story does have the moments where it gets dark even with the cute character designs like the moment at the end of stage 4 which I won't spoil. You can get the game easily on the PSN store today for only £5 and there's even a remake of the game on the Wii. Even with the short length this is one enjoyable gem to playthrough.
Speaking of namco:
This is a strange one. This is pretty much a platforming type game which a few underwater shooting levels. You have stretchy arms which go through multiple enemies but it only hits what enemy is closest to you, combine this with levels can get kinda difficult due to the fact once you die you use a continue and start back at the start of the stage (unless you hold down the II button while dying). It's not the best game namco has made but it is one that you can playthrough and see some of the wacky designs. Suprisenly Bravoman later appeared in Namco X Capcom and much later a 300 panel webcomic and short web series (funfact: bravoman is voiced by the voice actor of donatello from the nick version of tmnt) by Shiftylook. Though sadly the website has now been shut down, luckly you can see the bravoman comics by the bravoman volume 1 book from udon entertainment and see the web series on youtube.
