Hehe I did want the last level to be a culmination of all the mechanics so I'm glad you enjoyed it! This is also my very first time coding enemy AI, initialy the enemies of weaker colours were supposed to flee from the player but due to time constraints I couldn't make it (that and it would require me to remake every puzzle again!)
Initially the enemy AI only killed you when moving away from you, but it didn't make sense to me that, if the player is weak to an enemy, that the enemy just lets them approach and doesn't do anything on their turn! I'm happy enough with how it turned out!
If I do get around updating the game I do intend on explaining that better in the tutorial levels, anyhow tysm for playing and for the descriptive feedback! :D
