First in advance: You mentioned performance problems on older devices. I have high end specs, but realized the issue only persitted in Fullscreen where it literally was unplayably laggy but was fine in windowed mode. Maybe it helps.
For the feedback: Fun little game that made good use of the limitation! If you want to develop it further I could see some overcooked timed action happening and maybe some elements that make it harder or make it ahrd to keep the cake in frame.
Overall fun and cool looking game!
