I'm probably not the first nor going to be the last but this game makes my brain hurt but it is an amazing game i really enjoyed the first one and feel that you (IOJOE) really added a new depth to the game by adding the math concept to.
I quite enjoy this game it has all the componets all good games need(even if it is in it's alpha stages.) Some suggestion are like people have said more monsters and like holyangle12 said bosses would be cool, being able to save would be another, maybe adding a "food" like maybe berries you could find and eat i am getting a little quesy in the beginning eat hearts 0_o. Oh and what is happening when i toggle caps it does some lock in my inventory.
This should be fixed now! It might take a soft reset to do it though.
