Thanks for taking the time to play our game. As with any game jam game it would have benefited from some more time to add additional clarity to different mechanics. The boiler did only need to be filled once (hence why it looked full) but we clearly missed something so it seemed the text kept appearing leading to confusion. In hindsight maybe we should have added a objective tracker or something to keep people on the right track but you only figure this out afterwards. Either way, thank you for the review and taking the time to play the game =)
