Fun little game! Things get pretty tough, but there's a lot of health so it seems to even out. I'm a little curious what it would be like if the player would shrink on hit instead of grow. Getting hit seems to snowball into more hits just because the player becomes larger and slower. This isn't a criticism though, I'm just curious how different it would feel. I like the base speed of the ghost as it is now. The graphics are simple, but effective. Nice work!
