This is a really unique and interesting game. After dying a few times you start to get the hang of what spell is good for each situation. Getting Fever means you can start spamming the homing diamonds, which is awesome.
Not sure if it's just my tablet (lucky to have one) or working as intended, but I always have to tap the map first, then start drawing, while on mouse I can start immediately. I can't spam the line as quickly as I'd like with this :(
Either way, awesome concept, and I love the sprites and charm of everything. I hope this gets expanded upon, because it's surprisingly fun!
