Fun little game, really good especially for a first jam! The idea was very similar to our game. Last level was a bit annoying with the physics, maybe some tweak there would be good? Also the music is really really good, why set volume to 0 as a default :D

A neat little game. Very nice retro pixel graphics! I’d love to see the game expanded with more levels, puzzles, and a bit more variety. Nice work!

Also, when you build a game with Unity using the “Stand Alone” option, you need to build it 3 times (once for each platform). By default, you will only be able to build for your OS but you can use Unity Hub to install the builder for Mac and Linux. That said, if you build for WebGL you will get a lot more plays, feedback, and ratings.

Nice one, I like the gameplay, and the last puzzle is quite challenging~
Using the tile shape as a hint is also a nice touch :p

While playing I noticed some issues. First the player jitters when moving make sure to use the LateUpdate or FixedUpdate function to set the cameras position to the players position and second the colliders of the boxes make it feel uncontrollable because I suppose they are not a rectangle which makes it hard to place the boxes precisly. But I think the idea with the hidden Key "E" in the level is a nice touch and is pretty creative and the puzzles were ok. Well done considering this your first game jam!
