Really nice but at the start i advice you to give the player two boars to fight instead of three. And keep the hp of enemies at 100. Maybe for the èlite boars, give them 200 or 150 hp max
Difficulty has been an ongoing discussion since release. The feedback on the initial version was almost unanimously that it was a bit too easy, which led to the current difficulty level. A lot of it comes down to personal taste as well: it's a bit of a "can't please everyone" thing. But I think it's about where I'd like it to be currently. Not ruling out some minor tweaks in future though.
