Hey nice job! I only managed to beat level 6 it's certainly a skill issue. I think what the game could use is a few extra lives. Even if I just had 3 chances total to get as far as I could, it would make the game a little more forgiving. One mistake sends you back to the beginning, so that can be frustrating for a player. I also noticed that your blue circle was jittering around the target location, I'd guess because it was bouncing back and forth across the target position without ever reaching it. I recently learned about the "move_toward" function, which allows you to pass in the target location and the rate at which the position (or single number) should be adjusted toward that position. What makes it so useful is that once the position reaches the target, it will be exactly at that place, so you won't get jittering and you can check more easily if it has reached the target position.
Great job, congratulations on competing in your first jam! Hope to see you again in the next one!
