Can't thank you enough but this is a very good feedback! There is truly a lot of stuff that I need to improve on. My guess was the balancing before reading, and it's indeed the case it seems. The energy requirement of actions is another place where I really need to work a bit more on. Given that it's likely that you wouldn't spend much after purchasing the powerful items and fully unlocked the map, having more than enough is definitely a problem.
As for the claymore thing, I guess given the game is never about the weapon (as a weapon) in the first place, it surely is not doing a good job connecting the claymore and the gameplay. And that's 100% on me trying very hard to fit a name to the pun on SMoC :(
Anyway, again thank you for the feedback and glad you enjoy the game!
