Thank you so much for playing and specially for your feedback! Really appreciate it!
Trust me there was a plan for all the elements you interacted with and mention (level transitions being one that I still tried to squeeze at the end but was unable to)! Sadly I took too long with other aspects that perhaps didn't need to be perfected to be functional.
Regarding the pickups, much like the candy corn, they were based on our halloween candy but I tried to make them more generic.
For the game loop, since I was only able to finish the item pickups I modified the loop a bit to end after you pick up a few of them, so that front you were doing good :)
Unfortunately the more spooky bits were left undone (enemies, bosses).
So in the end, ideally this game would have had enemies and bosses that would be different in each stage and themed around spooky monsters. You would indeed be able to grab and drop enemies to the big hole to score points and clear the stage. The enemies/bosses would also be the things that would cause you to lose health.
It was ambitious to say the least hehe.
Thanks again for your feedback and for playing! :)
