I've needed to fix those jello spawns for a while, I'll be doing that soon. As for the swords, they should only flash when thrown (to make them easier to see), if they flash when not thrown, then I probably forgot to update this version :/
1. I'm not too sure, if it's necessary I will (it adds a bit of urgency to clearing rooms).
2.There will be more than one boss for each floor. I have some new ideas for first floor bosses, so I'm not sure I'll add the pirate ship boss back, and if I do I'll be redoing all the art and animation for it. But I'll finish all the other floors first before I add new bosses to existing floors.
3. The floor themes right now loosely follow the food pyramid, the first floor being sugary treats and so on, the second is meat, the third is vegetation, I'm not certain on the 4th floor yet. But no, there will be no Milk floor :0
5. I'm not really sure what your asking so I probably don't know :D
Sure, I'll write the version next to the name.
