Speedrunning and Pony Island Pony Island
Pony Island is very speedrun-able. The game requires a lot of quick thinking and quick manuvers to obtain a quick time. The game can prove to be challenging when dodging enemy projectiles and when completing a complicated puzzle. There is also three different categories that could be created for this game: any%, all-tickets%, and any% (No Major Skips). Both require different strategies to obtain the best time.
Difficulty, knowledge, and time
Difficulty Pony Island can be very difficult at times. Pony Island is very skill-based because it requires great accuracy and speed to speedrun efficently. Choosing the option to save time will likely require you to take on a harder challenge. Also, completing puzzles in an short amount of time requires very quick manuvers.
Knowledge Pony Island requires a lot of knowledge in order to complete. The game has over 20 puzzles, which all have unique solutions. You will be required to memorize how to beat every single puzzle in a timely fashion.
Time Pony Island does not require a lot of time to run. You may spend around 1 hour and 30 minutes completing a speedrun if you are learning. Faster speedrunners will likely take only 1 hour and 10 minutes or below in order to complete the game. All-tickets% will require more time, simply because you are required to hunt down all the tickets in the game.
Recommended tools for Speedrunning You could speedrun Pony Island with just a stopwatch or a web-based timer, but some tools will make your life easier and more organized, and make Pony Island more enjoyable to speedrun.
Here is the list of programs I recommend you aquire:
Open Broadcaster Software - Open Broadcaster Software is free and open source software for recording and live streaming. Doubles as a recording software. Usually, in order to submit very fast times or world-record breaking times to databases, you will be required to have a video of your run for verification.
LiveSplit - A sleek highly customizable timer for speedrunners. Supports SRL racing and split comparisons. Tracks how far ahead or behind you are of set checkpoints. Will be required for having an accurate time of your speerun.
These tools are free to download and use. I recommend using these tools for more professional and organized speedrunning, especially if you're recording or streaming. A list of tools can be found at this link: http://www.speedrunslive.com/tools/ • Alternative resources: http://www.speedrun.com/resources
Also, if you're new to speedrunning, I recommend learning some terms used commonly by speedrunners. Here is a link to a list: http://www.speedrunslive.com/faq/glossary/
Before beginning any speedruns In order to have a legitimate run, you will need to start completely fresh. No save files, no anything. You must also set your graphics settings to medium or high. • To clear your saves, select "Options" in the main menu. Select "Clear Save Data" and then select "Yes". Why must I do this? • Pony Island stores certain information while you play it. This information can alter another playthrough of it. Characters will recognize you, and will say different things and such, which can result in more or less text to skip. This will give speedrunners who have already completed the game once an unfair disadvantage, so it's required that you start fresh. • Setting your graphics settings to low uncaps the frame rate, which makes some stages faster than others. This gives people with a higher frame rate an advantage, so it's required that you have your graphics settings on medium or high.
Any% | Act 1 
This category involves using a secret that will skip the majority of Act 2
