When the slime(?) boss explodes into smaller enemies, I had one of them spawn on the wall, not the platform we were on.
The other benches I found to be solid, but the one in the icy area, I can walk through.
(It doesn't let me post screenshots for some reason)
The movement and exploration feel great and I liked the bosses. The combat with the regular enemies feels a bit clunky on the other hand, it felt pretty easy to get caught up in an enemy and get chain hit.
Also having keyboard customisation would be nice, since not everybody has the standard QWERTY style keyboard, and the preset controls don't align with how my QWERTZ style keyboard is.
