Thanks for playing our game. I appreciate the feedback, the one way platforms work a bit strangely generally I found if you're inputting a direction as you reach the peak of your jump onto the platform you'll catch on it if that helps any.
Good point there about the slow zones a different effect should probably be used to avoid confusion.
The intention with the colour change initially was to have it reset when you respawned but after spending many hours trying to get that to work properly I just couldn't quite work it out in time.
My artist actually made a cute little magic lamp post checkpoint but applying all the art at the end of the jam became a mad dash and I couldn't get everything in on time unfortunately. Once results are in for the Jam I'll upload a version with all the missing art. Thanks for letting me know about the broken buttons I'll have a look at those too.
