I think this is the most important game mechanic for a Mistborn-based game. Which is why I started there and wanted to tell you about it.  The iconic steel pushing and iron pulling are a perfect representation of the balance in Allomancy. Being a Newtonian-like magic system it works great for game mechanics.

As you can see, the force application equations are pretty straightforward. However, calculating the direction of those forces (The blue lines in the game) was not as easy. I had to go back to trigonometry to figure it out.

Now, finding the right equations to make the feature come alive wasn't the only challenge for this feature since the parts are in motion. For example, the equation changes if the character moves past the coin. Making sure every game mechanic worked from all sides was a bit of a mess.

In the end, it was well worth it. Now we have a fully dynamic steel push game mechanic. You can use this innovation feature to fly and toss coins. Clicking on any blue line will apply force following the "For every action, there's an equal and opposite reaction" rule. This means that if you push on a coin, that coin will fly away. If you push on something heavier than yourself you'll be the one doing the flying.

The iron pull game mechanic works almost the same way. The only difference in this innovation feature is you apply the for in reverse. Be careful, you can hurt yourself by pulling too hard on coins.

While the coins do some damage, keep in mind that those will barely bother the Kolos. So, I'll be talking about the combat system in the next dev log.
