I thought this was very unique. My girlfriend laughed at me dying over and over. :/

Hello! It's nice to see another game made in Gamemaker! (I made my submission with Gamemaker too.) First things first, this is a very cute game and I love how it looks despite the limitations, but I don't quite think you stayed within the 10 color guidelines! Each shadow gradient counts as an individual color according to the host of the game jam. Even so, it looks awesome. One major problem I had was that your game crashed and ran an error message after I ran around for a bit and threw some skulls.  I coped your error message for you so you might be able to see what went wrong. Other than that, it was a touch hard to stay on the path especially since the character moves slightly further than you tell it to with the arrow keys and it was difficult to aim and hit the ghost. It would be awesome to see this game where it played easier and perhaps with some power-ups of some sort to give it flavor! I know you said this is a very rough Alpha build and I respect that, and there is definitely a ton you could do with this idea! Can't wait to see the Beta, and keep up the good work!

Here's your error message!
