Thank you for your kind words!
The axe definitely ended up overpowered, since I originally made it with a much longer wind-up time. That didn't really feel good to play, so I made it much faster... at which point I should probably have revisited the damage value instead of building the entire rest of the game around it. Plus, I personally love this style of weapon in games, so I guess I just couldn't resist the temptation to make it too good. :)
(Alternatively, I could probably have made the claymore an intended upgrade earlier on, and have an even stronger "straight sword" type weapon as an optional secret. Although, at that point there would also need to be more level to fit all those items, at which point there should probably also be more tile variety, so...)
As for the enemies, I think that's mainly just an issue of only having 2 enemy types (two for the overworld and two for the cave, one being just a reskinned overworld enemy). Although, you could also say it's a gentle way of nudging the player to explore a bit more if they struggle with the cave, because if they had found every optional item up until that point, it should take a regular enemy 5 hits to kill them.😉
But yeah, if I had spent more than a week on this game, adding more enemy and weapon variety would definitely have been my priority.
