oh my god, thank you so so much, I agree the controls are weird, you're absolutely right, I should have added more stuff to the dice. I hope you noticed that the number they read is the number of monsters spawned.
Also the bullets automatically reload after every 100 score points, it's in the tutorial on the beginning! Although a big block of text isn't really going to make people stop and read.
Thank you very much for your wonderful feedback, I'm grateful
