Vaporum and Vaporum: Lockdown - real time blobbers (there's no party though, one char only, so technically not blobbers, but who gives a fuck), very similar to both Grimrocks in terms of gameplay. Slightly better graphics, tougher fights, decent puzzles, great char customization that gives replay value.
Seems that for some reason both games are not too popular here, while LoGs get a lot of love, dunno why - Vaporum is fucking amazing and I wholeheartedly recommend it.
