Lava SanctuaryX is a fairly standard pixel level, it seems to be a remake of an old level of this same creator, although I must say that I also found many similarities with the fire gauntlet level "Magmatic Sanctuary" of RadiationV2, however as the level is pixel style, it makes it more unique.

In terms of decoration, as I said before the level is pixel style, so I was not surprised to find some designs quite simple, however the environment that has the level makes the designs do not look neither empty nor overloaded, which is quite good, the atmosphere of the level I quite like, with dark and red touches, however sometimes it can be too dark, hindering the visibility of the player, I would recommend giving a little more brightness to some parts to counteract that problem, and speaking of visibility, I must say that some transitions are quite abrupt and can take the player by surprise, these transitions hinder the visibility of the gameplay. The truth is that the gameplay is quite comfortable in itself, it is readable and enjoyable, but sadly some shaders and visual effects make it difficult to read in some sections of the level.

Overall it's a pretty good level, but the overuse of shaders and transitions make the level a bit tedious to play at times.
