It may be a configuration on your machine that can't process the effect of the red layer on the screen when the alarm rings. :( After the Jam I will make a bug-fixed and more balanced version, maybe this one will perform better on your computer. :)
Oh no, it actually looks like that the whole time.
When the alarm rings it actually just covers the entire screen on a plain red square, so I can see even less of the game everytime it blinks
Again tho, my laptop *is* famous for being kind of a pain everytime I try playing jam entries, so don't worry too much about it x)
But I would be looking forward for an update if you actually manage to fix it somehow!
I can't really tell what tiles are solid or background like this....
