Like it the way you put this idea in place !
The mecanic of using that light both as a weapon and a utility item is perfect !
If I can propose some improvements it will be the following :
- A little tutorial at the beginning would not hurt. For example at the beginning I though enemies will be attract by lights so I drop it ! But nop they kept following me ! Haha. It can be used for a special kind of enemies I guess ;)
- Also some sounds and visual feedbacks when you activate a switch or burn an item. But I mean that's polishing so it's fine :D
Good job overall mate !
EDIT : Btw here is my game if you want to play it ;) https://itch.io/jam/gmtk-2019/rate/462077
