Thx for playing my game and giving me some constructive criticism! I'm happy that you enjoyed the characters and I do agree with you that the enemies were a bit too similar but sadly I didn't have enough time to think of some interesting character designs for them since the visuals are simplistic and just adding details seemed to make things worse but it can have ways for me to differentiate them more if I had more time to do some trial and error with the design. The attrition factor wasn't that much of an issue for me when I play tested it but it's sort of my fault for not getting other people to playtest my game since my experience playtesting is different from other people. I'm still happy that your able to enjoy my game and I'll make sure to learn from my mistakes when I'm making my next one!
