At the 'Not Preloader 2'. There is a text: "When it's full it will a scary face will probably appear and scare you or something. Maybe.". That is the description of the heart rate upgrade.
I think Dim thinking about the level looking, not the physics of the levels. That's why his level has a big amount of walls, but lack of physics meaning.
The shop/terminal should be can to sell some items, so if you already by a new gun before the goal to buy the new gun was appear, you have some money refunded after selling the weapon.
For survival mode, use Angel of Death and Skeleton for damaging slaves that want to build a floor, Locust Swarm for attacking a lot of slaves at the ground, Curse for cursing people if there is an high priest, Polymorph for turning high priest to sheep, Fireball to attack if you low on mana.
At the end scene, below that character there's a little text "But the Soul adventure has just begun." means that will be a game by SoulGame in Kongregate. :D
I had a oppennent almost 1st and I really close to him and close to the finish. I think I will lose, and I surprised I get an gold medal. That was the greatest battle for 1st position.
