Dungeon Crawler

I am currently working on a dungeon crawler.  I have made 1 level so far. 

Basically you have to navigate a dungeon and collect crates and rewards. I made a path for the player to follow to get to the end. The door will be at the end. Once the player collides with the door, they will be sent to the next level. 

I really don't know If i should make stages with levels, or just levels. Pls help.

Here's a screenshot:
