Thank you so much for the feedback! Theres a pause menu that allows you to go back to the main menu or to restart the level that will pop up if you press esc though we should have included that in the description. We are well aware about the core problems and bugs with this game and would fix them if we had enough time. For the UI layout we would definitely improve on it a little bit more post jam and add a minimap to show the layout of the map and thank you for bringing certain issues to light for us like the UI/UX layout!
