Really good proposition for a first game jam, congrats and welcome !
If I may, it could be bette to have dedicated time to bought items and timer could be more visuals (sfx or countdown in middle screen) during barrier placement.

Thank you so much for the feedback.
The sound effects during barrier placement completely slipped my mind, I totally forgot to add them.
I might make an update to put the countdown in the middle of the screen while it’s running and add some effects to it.
I’m really happy with all the positive comments and feedback, thank you very much!
