hey there thank you for playing our game!
First off we probably should've guided the player a lil more i have to agree that the clear goal is not highlighted enough or that our core mechanics aren't well explained to the player. We should've let the player know that they would be swallowed by darkness if they run out of mana (shooting drains mana and so you get less light to see around and eventually die if you shoot a lot).
Enemy ai had a major bug just before submitting and we decided to publish it now and polish it later.
For other bugs and glitches. We're aware of the problems and we'll try to polish the game once we have free time in our hands.
