The attempted graphics and atmosphere are okay, but the floaty controls are terrible making the jumps difficult to compensate (in a hard to control not challenging jumps way), added to this the jump itself is either ridiculously short or very high depending on if you press the button of hold it down very briefly, making any jumps between these virtually impossible. Added to this the jump gets interrupted by the scenery, needing the player to have to jump vertically upwards without touching any of the walls to be able to make the height of many of these jumps. As if touching them the jump is inexplicably shorter. All these issues make the jumping irritating and considering it is a platformer this is a major flaw in trying to play this game.
Bug wise, when holding up a shield some of the projectiles go straight through the shield and kill you, this is especially apparent when standing near the enemy. Also when collecting one of the keys in an area which was covered in spikes had writing to the right, attempting to read this (as mentioned earlier the jump caused an issue where it hit the ceiling trying to do a smaller jump) I died on the spikes and the key respawned inside the spikes which killed me even when trying to walk into them from the side to reach the key (which isn't how vertical spikes work btw), making it impossible to collect this key and thus making the game unwinnable from that point. If leaving the key on the body it should not leave it in an area you cannot get back from.
Overall a decent idea (even if the whole scary / unsettling atmosphere didn't really work) but in the end it was executed poorly having too many issues to make it worth playing again to get past the point where the game screwed me.
