nice animations and art style
good idea on game controllers (mouse + keyboard) and mechanic

I liked the game very much. The controls felt good and responsive, the music was relaxing and the art was good too. The core mechanic of the game was also quite enjoyable. Maybe having the dimension switch to be a toggle rather than having to hold down would've been  a bit more fun. Great submission! :) 

It's really a good game, you used the Jam theme very well and the level design is pretty good <3

It was a nice game.  Some comments. 1) Found it difficult to use both keyboard and mouse at the same time, especially as need spacebar and arrow keys (2 hands) + mouse buttons Could use alternate keys like up for jump and ctrl for change dimension etc 2) Voice was too soft, can't hear properly over the music. 3) Player can get stuck in certain scenario when the dimension is switched. 4) Player slides off the ledge if it is near the end. 4) why the need to press mouse button at the door? can just move automatically once reach the door 5) The pen and paper concept was well done

Really cool game. I can't rate the game but here's my feedback :)

Audio:

I enjoyed the background music quite a lot and I thought the voiceover stuff was really cool too! The only thing I struggled with was that the music was considerably louder than the voiceover. I could hear both okay on headphones but it may be hard to make out the commentary on speakers~

Mechanics:

Mechanically simple, but the whole thing was really smooth, I didn't run into any weird bugs or anything which is a feat in game jams! The only minor hiccup was if you're holding down the right mouse button on respawn in the 4th( I think? ) level, you just die on repeat  :D But this didn't impact the player experience at all.

Art:

I thought the style was really cool for 2D and the fact you managed to make the levels and the character animations in the game jam duration was really impressive. You stuck to a theme and you nailed it, good job.

Thanks for the fun!

Good Luck!
