A few remarks: 1) The particle limit is 235008. 2) Normally you can stack up to 5 layers (more layers turn the stack into BHOL) unless you're layering inside a wall like EHOLE where you can stack up to the particle limit. 3) Turning normal DEUT into *maximally* compressed DEUT is as easy as dropping down the console and typing !set life deut 65535
first off, yes, you can fit more particles that whats on screen, because there needs to be more particle slots avalible for things like protons. second off, ik it says 9.4k parts, but thats WAY more than what should be able to fit in that box, not even taking into account deut compression
and pixel layering is not a glitch afaik
you can't fit more particles than what is on a full screen, as that is the particle cap. also, it is only 9432 parts.
