Thanks. I agree about the attack. The problem is that a swing would require an animation and I suck at those, it would also be hard to scale the range of a swing and to make sure you can't hit enemies through walls (I could just get rid of the range upgrade but I personally think that it's the most important one). The current attack doesn't look the best but it's WAY simpler than anything else and I just didn't have time to improve it because I focused mostly on the procedural generation.
I do wonder if I could make a scalable slash, might look into it later.
