Created by a WWDC Scholarship Winner You need to use your brain to finish all levels. Some levels are easy but some are very difficult. The goal is to draw a sketches to guide the ball to release the balloon. The ball and all blue objects are affected my gravity. The first few levels are easy, but as you progress the difficulty gradually increases. There are multiple ways to solve each level, can you find the best solution? - Unique levels with more coming weekly! My Journey Creating Doodle Drop Doodle Drop unique sketching-based game where the user has to doodle a single object on the screen to guide the ball to the balloons. This fosters creative thinking and problem solving, and the user does not have to get bogged down in the intricacies of the game. Whatever they dream up to sketch has accurate physical properties due to the physics I’ve implemented. To achieve this seamlessness, I decided to use SpriteKit since it offers a wide range of extra functionality, including physics simulation, audio features and particle dynamics. SpriteKit made it convenient to apply forms of Newtonian physics to all actions that occurs on the screen, and so the game has an incredibly realistic feel. The force acting on an object is equal to the mass of the object multiplied by its acceleration, therefore accurately measuring the mass of the sketch was really important. The mass of the sketch is proportional to its density, so the heavier the sketch the more mass it has and vice versa. Due to the deep physics in SpriteKit, implementing this fairly complex algorithm was made easier. This makes the sketch behave like you would expect it, providing a smooth experience for the user since they don’t have to worry about it. Developing the algorithm for freehand drawing required a lot of hard math, which was done with curve calculations. Code efficiency was initially an issue but after reducing resource consumption and completion time as much as possible by removing unnecessary code and making reusable components wherever possible ensured a good FPS performance and a smooth drawing experience for the user. The complexity of the game and incorporating all the different features provides a smooth gaming experience with more precise actions and faster response times. It just works. ## Key features - Physics-based puzzles - Creative drawing gameplay - Unique levels - Increasing difficulty - Multiple solutions per level - Realistic physics simulation ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/doodle-drop/id1446355389/reviews.md ### 5/5 — Simple, Fun, and Clean! *2019-06-05, version 1.1* Love the simplicity of this game! It was challenging to come up with creative solutions to some puzzles, and that kept me engaged for hours! I think you could polish up some animations (for example the balloons don’t cleanly go completely off screen when the level finishes), and a start screen would be nice too (even something as simple as ‘tap to start’ and the camera pans down to the current level). Great game! ### 5/5 — Brain buster *2019-06-04, version 1.1* Loved the simple creativity of this game. I wanted an explanation of how to play in-game but honestly it was refreshing to have to figure it out on my own and think outside of the box. Love the concept and definitely want to see more levels. A start menu where you can choose to do levels over would be helpful too, would not be able to move forward, just back. Love it and honk you’ve done a great job of using gravity to make a game. **Developer response:** Thank you for the feedback. Working on updates, coming soon.... ### 5/5 — fun physics *2019-06-03, version 1.1* a cool little physics game! **Developer response:** Thank you ## Frequently asked questions about Doodle Drop! ### What is Doodle Drop?
