Thank you so much for playing the game and leaving feedback! I'm really happy you enjoyed it!!!! And thanks for the text emoji—I truly appreciate it! <3
As for the timer going to negative seconds—the thing is, when the timer hits 0, enemies stop spawning. After that, you just have to finish off any remaining enemies, and then the victory is counted. I probably should have disabled the timer at that point, but I totally forgot about this bug, hahahahaha.
