For a first game jam - that's good! I like the visuals they make the game feel heartwarming 

This is amazing for your first ever game jam, really well done!

Holy hell this is so good for your first game ever :) I definitely agree with Diego about ways of improving the UI and finding ways of explaining the mechanics in-game (I wanted to do that too in my game but not enough time lol). I really like your use of sound effects to respond to wall collisions, it would be really satisfying to also have sfx and visual effects to respond to getting a character to its endpoint. Also learning about how to do scene transitions such as a fade to black so we don't just pop into the next level are just some of the little ways of really improving presentation (hint: doing so involves a persistent game object)

It was simple but really fun! You should add a counter with how many moves it took to beat each level

In the how to play it says how to open the barriers, but a simple text the first time you encounter one would be nice as well

Level design was really good !

nice level design keep going !
