Thank you! I figured the game was small enough to be played through a browser, instead of needing to download it.
I should have prioritized the clarity for what the items and how they are used. In hind sight, there were so many different ways I could have made it clear when the generators are being used, mainly with sound, like you suggested.
Health bars were something I considered, but I actually prefer to not have them visible, as they kinda ruin immersion. Perhaps a simple visual screen effect would be smart to add.
I made the player move a bit slower because it's a part of the story about the miner that I didn't manage to tell in this jam. It will make more sense when I implement the full story.
Hiding can definitely feel broken at times, and it's mainly due to the enemy AI being programmed a bit poorly. When it stops chasing it will begin to wander for 15 seconds, but it usually doesn't go very far from that spot. Also, if you don't get a good distance from them before hiding, they will be able to kill you in the minecart. This is actually a bug, but it makes the enemies a bit more clever, so I kept it.
In the beginning area, it tells you the objective when you approach the rocks, though I realized that it can be easily missed by just not going near them.
I'm glad you liked the light mechanic! And sure, they are more or less zombie miners.
And no need to be sorry, the more shortcomings and issues that get pointed out, the better for the future of this game, which I will be continuing! Thank you for such a thorough review!
