This is the first time a flash game has lagged for me in a LOONG time.
Though the game itself is really cool, features awesome music and art, and feels good to master, there are some obvious issues with lag and responsiveness. Mid-air I can release the blast from the future cannon, change aim and fire again, and I might as well just hold the left or right arrow instead, as the blast only really has an effect the exact moment you jump(which is somehow sustained through the jump, but only in that general direction, and only if you don't change direction or release it(though you can change direction a little or use it to pole-vault sort-of. Look, you just made me double-paranthezise, you ♥♥♥♥♥♥♥). Don't ask me how that's supposed to work).
The lag intensity also seems to be proportional to the difficulty of the level, which can be very frustrating. Devs nowadays don't know proper lag placement.
Luckily these issues are pretty easily ignored, as you can pretend it's just a normal amount of false difficulty, because this game doesn't have it anywhere else. And since you just labeled them as false difficulty, you can relabel them to real difficulty immediately, because this game is REALLY forgiving. On most levels every single tile you can stand on is a checkpoint you restart from when you die, and you have infinite lives. A few ways of death will start you at the beginning of the level, such as death by fire or acid, but even this is pretty easily ignored, since each level is pretty short.
All in all, the weird controls and tendency to skip in time just feels like a challenge, because if the controls were good(and I mean navigation using the cannon, all the other ways of aerial navigation are much easier due to more intuitive controls, and walking/jumping is pretty perfect), the game would be way too easy.
So gameplay-wise, I can recap that as "the only game ever to have false difficulty feel like fun".
So ignoring gameplay, what does this game have to offer? Fun. It's quirky and ridiculous, and features an infinite amount of you, the main character, caught in a converging time and dimension loop that is apparently too complicated to explain in a short matter of time, but the truth is probably that none of you really know, since it's only been a matter of seconds/minutes since they were pulled into the whole mess themselves.
With great and funny monologues from the different insane versions of you explaining what's going on in the briefest and least explanatory ways you can imagine, and music that makes you feel like their explanations somehow made sense, it's definitely worth the money(of course relative to how much money you think such a game is worth. However, even starving children in Africa could buy this game when it's on sale and still afford their carribean cruises). Despite its flaws, it's a unique experience, and really fun. You don't feel this way after playing tennis OR castlevania. There, I've said it. The cat's out of the bag.
