Only buy this during a major sale. The game itself is quite mixed but still a fun adventure.
Pros:
1. Fun Co-op
2. The shooting mechanic is quite fun. The bow automatically targets a nearby enemy even if you don't zoom into the sights.
3. The Magic is quite fun to play around with
4. An arena mode where you can customise your experience
5. The banter between the two characters is quite fun

Cons:
1. Lackluster story
2. Lack of exciting music and is not memorable
3. No point in collecting gold as there's no merchant. It only works to increase damage, arrow capacity and such once you've reached a threshold.
4. Not many variety in weapons
5. Boss fights can be frustrating as they keep summoning minions.
6. No invincibility frames when dodging
7. Once an enemy combos you, you can't dodge until the combo ends. You're stuck there for a while
8. No inventory. Can't store health or magic potions
9. Some sections are too dark to see anything

Don't buy this if you're expecting borderlands mixed with fantasy. Buy this if you like cover shooter with magic
