Not bad...

First of all,i let you know that i only make the review about the engine,the A.I. and the fact that the player is supposed to learn from it.I'll start with the main game.There is one error:The boxes can appear in the walls.I know,it' stupid as the player to create a box in the wall,but nothing is blocking him/her to.That's one thing.There should be a health indicator.When the "bad" dies,he still stands until a box is created...If the player accidentally creates too much boxes,there should be a way to remove them instead of waiting.Oh,and when the "Bad" dies,the game should end or restart after a while.Now for the actions.The bad guy: The vertical speed doesn't need to be limited because he can't reach the top speed.I just wanted to say that but i know that in a real game,there could be a possibility.Personally,i didn't learn much out of this game because there's too much variables.In the create event,what you could have do in the code is put a comment beside each variables to tell what they do.There's a Hero object.It's hard to know what it's doing here because i have no idea what this is.It has no actions in it and it's not even in the room.Put a comment in a random event and learn me how it's created,what it's gonna do.All the variables are confusing me so i can't find myself in the coding.Maybe i am taking this game like a tutorial more than as an engine.Give me a comment and i'll try my best to make a better review.
I hope i'm not mistaking!
