Couple of comments on the game.
First of all it's very much completable.
Next, The movement for all the way until the dungeon is really slow, works well in the beginning but as there are no alternatives, it rather quickly begins to be not fun to move around.
Additionally, the difficulty of different zones starts to feel quite artificial when it is based on being respawned at the beginning of the level, that combined with lag and a couple of minor bugs along the way which makes you respawn more times than is necessary puts a strain on the game.
Small comment, the end of the cave looks like a stalactite looks like a stalactite, it took me a bit of time to understand.
The run and jump section is fun but I experienced recurrent minor lag spikes which completely messed with my rythme. This led to the section feeling like a chore due to having a couple of deaths feeling unmerited (that said, the being respawned at the beginning does work for this section, as it does for the running away from the spirits section, much more so than for the other sections).
I experienced a bug where on exiting the dungeon through the white door, I immediately died and respawned at the beginning of the dungeon.
Comment on aesthetics, the red clock and its animation are very very nice. A couple of other assets have something to them, a nice aesthetic (for instance, the mannequins, including when they move, the trees at the very end, the presentation of laughterworld, the trees at the very end). Most of it is very generic and copy paster, its fine in relation to the storytelling of the game, even works in its favour.
