So the idea is to tighten up the AI and behaviours of the goblins the deeper you advance in the game.

Here is an example fight with one such improved AI.
(btw. the buttons are now dark gray purple, less focus on it seems to fit)

Whats going on here?

Archers will make barricades on both side each having 1 hp blocking the player and his proactive while letting the enemy arrow pass above

Blockers shoot a rope capturing you for 3 seconds making you unable to shoot or use the cloud if you fire at their shield

Chargers have a 33% chance to use a jump button and attack in the upper lane
