Make sure all the buttons work before submitting, or at least the ones that ensure that the player can complete a game loop. But i'm guessing you already know that.
Now for something that might help you in the future. when making pixel art in unity you can click the imported image file and in properties set filter to "Point(no filter)" and Compression to "None", like so https://imgur.com/a/ZIwLltd this ensures that when scaled to a bigger size the image doesn't become blurry

Thank you for your feedback and helpful tip! I completely agree that there were some bugs and glitchy buttons in the game, particularly with the pause functionality (stupid bugs >:(). Due to time constraints, I wasn't able to address those issues. However, I see it as a valuable learning experience for future game jams! and I'm 100% gonna go patch those up once the rating period is over!
I genuinely appreciate your suggestion regarding pixel art in Unity. As someone who is still relatively new to Unity, I found your tip regarding the "Point (no filter)" filter and "None" compression settings very valuable. It's great to receive feedback and learn new techniques that can enhance the visual quality of pixel art in larger scales. Thank you for taking the time to share that with me! again thank you so much! I'm happy to learn such valuable info for my first solo game jam ^^
