So, you're using the bayonet tactic? It's a viable, if risky, method. 😅
When I get round to a proper post-jam version I'll very likely make the enemy a lot more challenging. It does matter what difficulty you play on, the troops you get on Hard will have much more trouble getting away with bayonet cheese (pun intended 😁 ) For jam games it's usually better to go with 'too easy' than 'too hard'.
