I liked the concept, good loop and consistent, clear art. I found a few bugs using the web version:
1.when duration reached 1:00 the timer stopped but i kept playing with most mechanics (except upgrades but i only checked that after I had more than $102 so maybe that's a separate bug)
2. Most of the UI was hidden until I clicked on the fullscreen button (from Firefox in MacOS)
PS: Good luck in the jam and if you have time please rate our game!
