Thank you! That really means a lot. Yeah I think the controls could have been mapped a bit better, I set it to those keys in the beginning of the week then never touched them again, I originally wanted to allow for button remapping but never got to it.
Also generally with anything running in your browser the Escape key (Which I think of as the 'traditional' pause button) is reserved so it's best not to use it. Like if the game was full-screen and you pressed escape it would exit full-screen and potentially pull the focus away until you clicked the game window again (Although I didn't even have full-screen turned on so maybe it's a moot point lol).
Anyway, I'm glad you enjoyed it! Thanks for the feedback.
