Very well done, its a Great Game made in 48 hours.
What I found in game that can be improved (Regarding your post):
- There were no collisions on borders of map, I could go beyond the map.
- Enemies killed (Wolf) kept going downwards as if a small amount of Y force was been applied to them.
- The Music Background should Loop
- The cool-down for the mp hp and speed were to small,It was easy to stay alive because of that.
Overall, was a great game made in a small amount of time! Great Job :)
