I got all upgrades available in the demo and couldn't get into the next floor because the auto collectors kept collecting but were so slow that I couldn't get all the ore in time. I would try to get the ore first but they would still steal some. Tried multiple times and it just would not work. Very disappointing....

During late game the explosion effect literally turns this game into a flash bomb. These type of high frequency flashing effect can actually hurt people, it's so bad I'm still seeing phosphenes after 10 mins resting from this game. Fix it or add seizure warning....

The frame rate of the 1F is clearly problematic, while the other floor are correct
