Too many spikes?

[Pyrite]

I try to make a level, made out of completely spikes and 4 walls. It crashes when I test-press enter. Why does happens?
Is not correct English order, but is understandable.

Too many entities (and with "too many", I really mean "too many" ) on a screen will result in a crash. I don't really feel like looking up the exact amount, but yeah.

Spikes is converted to an entity internally. Other things that do this are 1-pixel-wide quicksand blocks, and the one-way wall thingy.

In v.2.0, the min. number of spikes that makes the game crash is >500 and <521. I tested that. A room with so much spikes must be rare.

Do you mean you made a room with 4 walls at the outlines and floating spikes filling the rest of the room? That would surely have more than 520 spikes.  It really had, because the game crashed.
