I can tell you worked hard making this game. Making a 2d isometric game is not easy at all. You even managed to made an inventory system, all in just one week. Good job.
I do have some feedback:
- Movement with W,A,S,D might be better since it's closer to the Tab button to open inventory
- Sometimes moving to certain direction can feel slower than moving to the other directions, making movement a little bit stiff.
