Really neat game, i like!
It was weird how some enemies would require a different amount of presses despite looking the same. Like, one bird had only one slash to beat it, but the next one needed 3. It wasnt that bad, honestly, just kinda confusing.
I would keep the number of slashes consistent with the enemy type (bird = 1 slash, goblin looking thing = 2 slashes, etc.). It allows the player to better predict their next move, because they'll be ready for how many times they need to press the button.
Actually, maybe thats why the button presses are (seemingly) random? To keep the players on their toes? If that was the intended result, then you can ignore my previous yapping, lol. Good game!
