I liked the presentation a bit, the use of light and shadow was quite nice, though there was a serious problem in that the buttons shown to you in the tutorial were impossible to see because the shadows covered them up.
The concept also had a lot of potential, with the lantern giving you an attack, and two different forms of movement for when you had it or not, but the execution was very messy.
First of all the player is way too large, and way too sluggish and slippery. This makes it so basic platforming is annoying to do, especially because you keep needing to keep switching between holding the lantern and not holding the lantern in order to get around.
Second of all, the puzzles are all very confusing. It's not at all obvious what you need to do to continue, other than just running around in circles activating and deactivating torches until the doors forward open. The black torches also were not explained at all in the tutorial, only being explained after a level where you needed them to solve the puzzle, which I got stuck on because the torch I needed to switch was on the ceiling where I couldn't see it.
Thirdly the attack was basically useless. Despite using the mouse it only shot straight forward, meaning with the difficult jump controls it's extremely hard to land a hit on the ghosts. There was also a line about banishing them in the tutorial, but I never managed to do it even when I shot them twice with the fire. The fire also takes too long to reload, and there's no indicator as to when they'll reload, so I just had to wait around for no reason since it needed to reload for a puzzle.
Overall it's got a lot of potential, but it's so frustrating and annoying to play that I wouldn't wanna touch it again until it has a lot more polish and design work.
