I feel like the idea itself had a lot of potential and could become quite an enjoyable experience.
However, I did not find the game UI very intuitive, and I spent most of the time figuring out what I am supposed to do. What would help a lot is adding some instructions or descriptions of some of the objects that can be placed into the grid.
It is very likely that you didn’t have enough time to add everything you wanted. For your upcoming projects, I would recommend first making a prototype that is fully working and perhaps making someone else play it so that they can give you some critique, which could help you improve your gameplay. Then and only then, start replacing placeholder objects with actual assets.
I am sorry if I was a little too harsh in this comment, I hope it will help at least a little bit. Anyway, good luck with any upcoming projects/gamejams.
