Bubba Time was conceived as something of a munge between Solomon's Key and Braid -- and while the time manipulation elements are fairly minor, it is an excellent puzzle platformer in the mold of Solomon's Key.
By which I mean both that the levels are intelligently designed and also that this is by no means an easy game, for the same reasons as Solomon's Key; that is, while the puzzles are not fiendish, the platforming aspect of the game requires careful timing and intelligent planning. The result is frequent deaths within a level, both as you figure out the solution to the puzzle and then as you mis-step on the timing.
Not surprisingly, some of the comments on Kongregate complain about this aspect of the game -- something that's perhaps more revelatory about the casualness of most Kongregate players than about the game itself. Yes, it can be frustrating at times, but it's quite engaging.
The title bothers me; "bubba" to a Yank means "redneck" (unless you're Jewish, in which case it means "grandmother"). Presumably the Argentinian developers chose the word because the Kirby-like protagonist looks rather globular, that is, bubble-like. No good ol' boys drinking whiskey and rye here, however.
