Hey we saw your lets play on youtube and are glad you liked it!
From what we saw we really need some onscreen overlay to quickly tell people the controls and that the crates, barrels and enemies only drop health when the player is low on health. But we are glad you eventually found out how to shoot the minigun for yourself! Did you later try the charm mechanic with middle mouse? It is great fun also! We will see if we at some point in time iterate on this game idea and make a full game out of it with, though the current DungeonTracks is pretty long as well.
Thank you for recording!
