I was really surprised by this game, in a good way. I always wanted to make a game like this, where I guide the player through my train of thoughts. The game looks really nice, the UI is super clean, and I didn't mind it being a bit slow, although I admit I prepared a geek salad while playing (which explains a few burned popcorns). Sorry if this is weird. You started it.
I would have changed a few things in terms of mechanics for each idea, but I don't know if this is the feedback you're looking for. I was excited by the rhythm game idea, but as a player I really want to click on the beat, and this one was out of sync for me (offset, I had to click before the beat). I tried making a rhythm game before and had the same issue due to syncing problems. Not sure if this delay is by design or a software issue though, as I only tested it on my computer. Also when making popcorns, I would have liked a much smaller delay between each drop, as I don't really get the proper feedback for my actions (clicks get discarded). I know you need some delay to avoid memory/collision issues, but it's just how I felt about it.
Anyway great game once again! I'm glad you made it, as now I know what the idea can lead to :D I might do one on my own one day! Cheers
