This game is really not that good.
At first, it gives off an expression of it being a good game, but it is not. Firstly, it is kind of confusing. It offers no hints at what to do, or what way to go.
There is also this point where you get stuck flipping worlds and you're stuck in a continuous loop where the only way out is to restart the game. Then you have to go through it all over again.
I suggest adding some of those things in there.
I made sure it's impossible to be stuck in a continuous loop (It is hard to get out sometimes). The restart button was more of a guarantee in case you DO get stuck. As for the restart button restarting the game, that was actually a bug! Thanks for notifying me.
If the level design is too confusing for many people I'll consider adding some pointers and whatnot when you're moving backwards. (This is what I get for not playtesting the game!)
didnt like it that much, sometimes the flipping glitched out and hurt my eyes :/ it kept switching from up to down. i would consider you try to fix that, maybe make you jump a bit higher when you flip?
Now fixed. Considering it was a minor, barely gameplay changing bug, I guess fixing it doesn't break Ludum rules.
