I love the way the theme was used here, with an actual end to a timer taking you to a new beginning!
Also the art reminds me of Blackthornprod, which I enjoy quite a bit! I think it could've been more unique, but that's not the type of thing I'd concern myself with in a game jam, only if you wanna further develop this into an actual release or something.
There were a few issues I had with the game though.
The first is probably the most major issue in my opinion: I don't think you can "lose". You just get swarmed by a bunch of enemies and all they do is crowd around you. An actual losing state would've made this more than a walking simulator where you have a torch.
Another issue I have is that the game's music feels a bit unfitting, with just one track constantly playing all the time. Maybe keeping the same melody with slight instrumental changes as you go dimension-to-dimension would've livened things up a bit. Though I don't mind too much since you did only have a week to make this.
My other issues were more of control ones. The player moved very slow, meaning that the dash was my primary means of movement, when it really should be a special one. Maybe having some sort of recharge meter could help alleviate this, and also speeding up the base player.
On the subject of the dash, I don't know if it's just a me thing but I found it weird that the dash doesn't go in the direction of your cursor. I feel that'd make things a tad more intuitive. Or have options for both in the settings.
Though overall, I liked the concept & art and had a bit of fun here! I definitely wanna see what games you make in future. :)
