So 1st thanks that you like game. The thing you should improve is to not wander around a lot, try to go more straight and upwards. Also player dies everytime your lamp reach 0 power. (You can see how much power your lamp has in the right corner). You gain power from lamp by taking blue souls around map. Also each time u sprint you get better light and speed but also your lamp will lose power faster.
I encourage you to try to come to finish because you will probably like it :)
