Wow, I'm actually surprised you played the game to completion since I haven't actually done that! Yeah the scale of the map relative to movement speed was a problem I didn't foresee when I designed my levels, however I am glad to see that the game is working as intended since you were able to complete it!
You are the first commenting person that played it more like a survival horror which was closer to the intent of the game, and yeah the way I handled the mechanic is not as well baked as I would like.
I should note there is instant movement in the options but I would still say the maps are still large anyways.
I'm still certain I didn't have a bad idea, but I certainly didn't utilize my mechanics well enough.
Thank you for the feedback!
