I wrote out my thoughts as you play! To start out, really fun and fantastic job!
Here's what my notes were:
A little too slippery: maybe stop more on edges --- Future Nia comment: I didn't mind controls at all later on, so probably not a big issue.
Restart symbol not clear on first playthrough --- Future Nia comment: Maybe just have a blue bar that fills it up ala Smash? Not a huge issue though.
Maybe auto repick up magnet when run into it? I don't think it would change any puzzles, and it would make the magnet feel a lot more related to you.
Magnet only walls are good idea, but maybe make them look different, like transparent, so it makes more in-game sense why the magnet can go through
You're pulled closer to opposite sign doors, but you aren't pushed away by same sign doors? A little strange
Angled buttons are a neat idea, but you just also be able to jump on them rather than fall off
Puzzle with falling magnet was a good aha moment because it required experimentation: I said "aha" out loud". I discovered something important by accident, which is always nice!
It registers mouse clicks when you're in a different window, leading to character throwing as soon as you reopen
I HAD TWO AHA MOMENTS in same level! It seemed impossible, and then it hit me!
It's fun to repeatedly rhythmically press F and swing magnet back and forth through the doors: maybe make that a thing you do? :p --- Future Nia Comment: Yes you do!!
Spawn out of door of previous level? also kind of fun to run through to new door as a victory lap though
Now I'm pulled to door of different sign? This didn't happen earlier
I'm saying "ohhhh" a lot and that's good :D
Kind of weird that the magnet has only one pole---it's a game about magnets, but the magnet does something physically impossible, ha ha. It's a magical magnet!
I'm thinking! :DD
Sometimes a bit boring, but I think music will INSTANTLY solve that problem :D
I said yeah!
I'm talking out loud! :OOO
"ohhhh it's solved" the solution I thought it would be wasn't it, ha ha. But the correct solution was very enlightening that I stumbled into. Blocks (well, doors in this case) can block other blocks!
I said "clever!" :DD
I really do think run auto pick magnet will make the game control so fluidly.
Maybe make it so you can throw magnet while moving? Would be a bit less choppy.
Hope this was helpful! Thank you for releasing this demo! :D
