Not sure if this has been mentioned before (I did a couple of searches, but they resulted in nothing), but here goes.
In the (EDIT) second of the jelly garden levels, in the beginning (right after the party button, in the room you have to go in a circle to get the stone to put on the button to open the gate), if you kill the jelly cubes by where the bushes are (next to the gate), the drops float waaaay high above us. We can still pick them up, but I just thought it was odd that they float like that, so I figured it would probably be worth mentioning in case no one had caught that.
I don't think it's a "high priority" bug, as the drops are still attainable, but it might throw people off, so it's something to consider. :)
As an aside: Thanks devs for all your hard work! I'm really happy to see that the suggestions from the forums, and the bugs that are being pointed out are being looked at, and either implemented or fixed. I really appreciate it. :D
This can happen in many situations. A good example is the red guys on Graveyard levels. When you knock them onto something elevated they will go on top of it. Seems like height is only a visual aspect in some cases.
