Very cute game. The art is great. I'm really liking the expressions on the axe guy and the pig.
The game has the right level of challenge IMO. I was able to make it through with 4 deaths.
To improve the game, I'd suggest:
- Moving the button prompts closer to the pig. After the first few times, I found that I was only staring at the button prompts, which feels like a waste to the rest of the nice looking game.
- Perhaps you could introduce a variation which requires mouse-based input. To mix up the challenge a little bit and to reduce the concentration on the button prompts.
