It's a really good game! But I really think the amount of Monsters should be less and slower.
In my first try, I just ran away constantly and couldn't get to any shop without getting severe damage..
In my second try, I knew what I had to do, so I bought a lot of weapons constantly, but I still got crushed at the end, because monsters came from all sides and I couldn't move anymore. So the same problem again..
I still really liked the concept and had a lot of fun! The graphics are fantastic for a game made in 3 days and the Music is really good! ^^
I'd love to see this game in a more polished or even finished state after the jam is over!
