The reason the fight against the cop ended up being so difficult is because we didn't anticipate the player wouldn't be at LVL 3 by the point they got into the fight, so you didn't have your third skill on Alex, which we balanced the fight heavily around. It also had an issue where you couldn't gain the extra skill from the Radiant Shard because of that, so the fight was only won because Carll ended up being enraged, which gave him spawnObject(lghtn) to stun the cop with. His undodgeable attack only comes up if you don't stun the cop for long enough
We're tweaking things here and there to make the mechanics a lot clearer and more well explained in the tutorial, which was massively overhauled since this version, and includes giving you the third skill as soon as LVL 2. Enemies are also a lot less hard to kill, now, with less health and a new piercing mechanic
This let's play series was really helpful for finding weak spots in the game for us to improve on, so thank you!
