Nice game! I like the pixel art and Halloween vibe here. I didn't understand what most of the placeable blocks do. I noticed that you have to create a maze to funnel the enemies similar to a tower defense game. I also think there are some balancing issues, because I was never able to kill an enemy or get any coins. Overall, it seems like there is a lot going on here gameplay wise. I recommend gradually introducing placeable blocks and abilities to help onboard players. Good job with this submission!
