Great game!
I won't say what so many others have said. I, too, expected arrows to pass through enemies and hit multiple in a row.
Different enemy types would have been nice.
I feel like punishing the player that hard for an additional roll isn't great. It's an instant death sentence. Maybe deduct the last rolled die and disallow further rolls instead? With a 6+4+6=16, it would be tempting to roll once more. If I do and I pass 20, deduct the last rolled die (6) and let me play with the 6+4 instead of with no dice at all.
Some sort of improvement system would be nice. The enemy hordes always improve, but we never do? Also, it might be fun to encourage unbalanced stats. Right now, evenly distributing stats seems good, but playing with lots of ammo and health in one game but little speed and being a speedy boy with just one arrow in the next seems fun, but it isn't ideal. Players will optimise the fun out of games.
Thanks for participating. Hopefully we'll see you at the next jam!
