What worked:

The visuals work really well and give a creative and unique look to this game. The feeling when the light finally runs out of stuns is pure bliss. I now know how final bosses feel when I keep foiling their plans.

What didn't:

If I don't keep the light in my field of view, there's a good chance I'll take the wrong dead end and have to go all the way back up, losing the light. This is fine as a lose condition innately, but how I got there ends up being making one mistake, then losing to "pick-a-door" when I get to a fork. This part doesn't feel very good. Maybe add a trail to the light? Also giving the boss some skill based abilities to help could be a fun idea, especially if you plan on expanding the idea. This way there's some counter-play (unless I missed something) to being stunned repeatedly or taking the wrong path.

Bugs:

Didn't see any.

Great job!

Really great game!

This game has a really fun concept, and I think the fisheye lens adds a lot to the look of the game. My main criticism is how tight the timing is to hit the light when you catch up to it. It's hard to tell when I should be hitting the attack button, since there's no attack animation or anything, and getting it slightly off means that I completely miss my opportunity to attack, which is frustrating after chasing the light for ~15 seconds. That being said, if it was trivial to hit the light whenever it's coming at you, then the game would probably be way too easy, since it's not too hard to corner the light. Maybe it would need to have more health or go faster as it takes more hits to balance it out? Also on a separate note, there was one time that I was on one side of a wall and the light was on the other side, but I still got hit and stunned by it, so there might be an issue with the size of the light's stun hitbox. If you can come up with a good way to lessen the annoyance factor of the light constantly stunning you without making the game too easy, then I think this will be a really good game!
