This is pretty clean. I like how you kept the minimal style through the audio, art style, and gameplay. The main mechanic is pretty simple but the nuance of maneuvering boxes and altering your jump height leads to some neat puzzles. Well done.

I like the puzzles. The marginal adjustments to weight work very well.

I think the spikes are just a bit too unforgiving. Or maybe I'm just butterfingers.

A little music would have been nice, also.

Concept is amazing, physics is amazing! The keys for picking up and dropping boxes were a little confusing as they were different, but altogether a really well-made and well-working game!

The sounds are amazing and it's very pleasant to listen to!  I would have liked to see some more levels as they were very fun.  There is a bug where if you press space and then pickup immediately after  you maintain your original jump height with the book, was able to get the WIP map halfway done with this.  Maybe a little music too but nothing that clashes with the sounds.   Overall really fun just needs more levels and more mechanics!

Great concept, and excellent use of limitation! Weighing yourself down to manipulate your jump height to avoid ceiling spikes was very clever. Would love to see more post jam!

Nice game. I liked the feel of the game and the detail of the sound changing with the amount of weight. 

I like how you utilized the mechanic for the game. Especially using the weight as a means to getting through the spikes. There was a bug where I dropped the box and it fell on the outside of the map, so it would of been nice to have a restart button. Overall though, this game was pretty nice.

I really like the game and Mono chromatic Art style.

Also I would Really Appreciate it if you played my game.

I like your concept.  There are some collision issues. Character kept getting stuck on certain areas.

Nice work! I really like the artwork and unique sound choice. I had some issue sticking to the side of some blocks though.
