The crafting was pretty good, but the materials shown on the left side of the crafting window should be listed with their icon instead of their name, to be able to match them to the required mats in the crafting list on the right. That was a bit confusing.
Also, the audio balance needs improvement. The sound effect for picking up items was way too loud compared to the background music.
Finally, the red color you used in the second map is very harsh on the eyes. Try a less saturated color for a better result.
One last tip: always keep a backup of your project files!
