Everyone loves the Jumping Flash games, right? The early Playstation releases that brought a splash of colour to the normally dour world of the first person shooter, their only big downside being the draw distance that had barely improved from their genetic forbear Geograph Seal, and restricted the player's field of vision to barely a few metres in front of their noses. Luckily, there was another sequel, released only in Japan in 1999 that corrects that problem! Unluckily, it's also a very, very boring game to play.
As I just mentioned, the Jumping Flash games stood out amongst other first person shooters by being bright, colourful games, set in fanciful wonderlands. They also stood out by not only have a jump button, but by letting players use it to triple jump to incredible heights. Robbit Mon Dieu, unfortunately does away with almost all of the shooting of the previous games, and in fact pretty much all of the action and even the challenge of those games along with it. A first person game focussed on platforming is still a fairly novel concept, especially in 1999, but not like this.
I feel like the problem might lie in a shift in the demographics the publishers were targeting: as a game aimed at the under-fives, Robbit Mon Dieu would actually be one of the all-time greats. It sees you fulfilling simple tasks like delivering a package to someone who lives up on a floating island, tackling obstacle courses, diving off a high platform and falling through hoops, and so on. There's a few stages that technically have you shooting things, but since those things don't shoot back or offer any other kind of resistance, it's hard to really consider them shooting stages.
Though it's odd that they'd aim a game at such a young audience and use characters from a pre-existing game that was a few years old itself at that point. Furthermore, there is a lot of text in this game, including menus, mission briefings (though obviously, most of the missions are simple enough that you can easily work them out without being able to read them), and story text. So I'm going to assume that the game was aimed at pre-existing Jumping Flash fans.
And with that in mind, it's a total failure. Unless the aesthetics were literally the only thing that drew you to the Jumping Flash games, and you don't care about how they play, Robbit Mon Dieu is not worth bothering with. It does look amazing, but that's pretty much all it does. Not recommended.
