When comparing Allegro vs Pyxel Edit, the Slant community recommends Allegro for most people. In the question“What are the best 2D game engines?” Allegro is ranked 15th while Pyxel Edit is ranked 55th. The most important reason people chose Allegro is:
The Allegro community has produced a lot of great tutorials and resources. Allegro [Wiki](https://wiki.allegro.cc/index.php?title=Main_Page), Mike Geig's Allegro [Tutorials](http://fixbyproximity.com/2d-game-development-course/), Rachel Morris' [Tutorials](https://www.youtube.com/watch?v=E4RqHtEAAds), CodingMadeEasy's [Tutorials](https://www.youtube.com/playlist?list=PL6B459AAE1642C8B4&feature=plcp).
Ranked in these QuestionsQuestion Ranking
Pro Supports desktop and mobile
Support for Windows, Mac OS X, Linux, iPhone, and Android
Pro Good engine architecture
Allegro is well designed, easy to use and has many useful features.
Pro Good documentation and lots of tutorials
Since it has been in development since mid-90s with hundreds of people contributing to both the engine and documentation, it has all of its bases covered when it comes to standard support.
Pro Per-platform library optimization
Allegro uses DirectX for Windows, and OpenGL for other targets.
Pro Freedom to implement your own game engine
You are not bound to the limits of existing game engines, and you can actually implement your own engine.
Pro Intuitive UI
Pyxel Edit is widely acclaimed for its ease of use.
Pro Supports animations
Tiles can be animated within Pyxel Edit, with "onion skin" frame overlays to assist in making smooth frame transitions.
Pro Tileset extraction
Given an image and specified tile dimensions, Pyxel Edit will extract a tileset with no duplicate tiles. This mostly works for flat images though. If you feed Pyxel "finished maps" you will still get a lot of duplicates.
Pro Tilemap serialization support
Tile-based images (maps) built in Pyxel Edit can be serialized via XML or JSON for easy import elsewhere.
Pro Cheap compared to others
For only $9 (£6), this is one of the cheapest but also one of the best pixel editors out there.
Pro Live tile-update
Instantly see if your tiles are tileable and/or seamless and fix it easily.
Pro Indexed tiles can be used for reusing objects in animations
Con Learning curve for hobbyist developers
Hobbyist developers coding alone may experience a learning curve with Allegro of about 200 hours (if you are rusty on C++). To learn quickly, see Mike Geig's tutorials at Fix By Proximity. This learning curve may be fine if you are considering going professional, but are still unsure.
For hobbyist developers not planning on going professional, you may want to look into a complete 2D game engine, rather than a coding library. For example, there are "non-coding" engines that provide support for coded plugins or scripting. But, if you are a dedicated hobbyist planning to use Allegro as your coding library of choice, you can still develop great games as a hobbyist.
Con Isn't great for C++
If you are a fan of object oriented programming, and want to use this library, then the chances are that you are going to be creating a lot of wrappers for functions in this library.
In short, if you're a C++ person, it could be recommended to check out SFML instead.
Con No Linux version
There is no Linux version of the editor.
Con Free version lacks features
The free version of Pyxel Edit is an outdated beta. It does not receive updates.
Con Proprietary, closed-source software
This software does not respect your freedom.
Con development has stopped
Con Mac version is dependent on Adobe Air
The OSX version of the application requires Adobe Air to run.
