Click to shoot. Don't let the squirrels get to you! The first three times you level up the level gets longer and the arrow rotates faster. After that, the squirrels get smaller so they are harder to hit. After beating level 8 it stops getting harder, but you can go ahead and keep going. Try to beat the record! I spent a stupidly long time creating a system that stores everyone who has played along with the achievements they got using lists, but then I realised that there is no such thing as "cloud lists."
I coded the first draft (Can you use first draft in games?) of this game in an hour to see how fast I could code.
