Hi Arthur I played 9.0, I played for a while and managed to get to the boss a few times, I was able to try out a few strategies for defeating the enemies in an order I felt was best for me, the map is designed very nicely! but I found it too challenging in the end and didn't have the skill to defeat the boss. The mechanic is great! It feels fast paced, and attacking enemies feels good. One thing that I would suggest is I was mostly challenged whenever I was faced with more than 2 ranged enemies, this was where I struggled with the game the most, also if a ranged enemy was either side of me. Other than that I enjoyed playing and really look forward to seeing more!
