Pros
Pro Joystick and multi-touch support
Useful for mobile games and soon consoles (OpenFL has a console port in the works).

Pro Crossplatform testing/releasing
HaxePunk uses OpenFL which means you can compile to just about every device. A lot of the rendering code has been optimized so if you use HaxePunk’s graphic classes you are pretty much ready to deploy on any target.
Pro Generic entity system
A generic Entity system that only uses what you “attach” to it. If you need collision masks they are available but if an entity doesn’t need to collide with anything then simply don’t add a mask. Same goes for graphics.
Pro Written in Haxe instead of AS3
This comes with blazing fast compile times, proper static typing, multiple output targets, and a powerful macro system.
Pro Multiple collision masks
HaxePunk has added several collision masks beyond what FlashPunk had including a grid with slope values, circles, and polygons. This is in addition to FlashPunk’s tile grid and hitbox.
Pro Tweens
Tweens are available just like they are in FlashPunk. If you need to interpolate values for sounds, movement, etc… it’s probably already available as a tween. There is also a VarTween that lets you interpolate any value you want.
Pro Light weight
An amazing minimal download size at around 100mb.
Pro Easy to use
Engine 001 allows you to get to making games quicker since you aren't putting allot of time into figuring out complicated interfaces.
Pro Visual scripting
By using pre-build behaviors\actions and more you can 'program' your game by simply 'linking' they in the editor.
Cons
Con Messy / fragmented documentation
Not a lot of documentation is available.

Con Small comunity
It’s a small but growing community.
Con New tricks for getting more money
As it doesn't have enough tutorials, and they don't wanna make more, so they just add some new services about one on one help which that cost 40$ for an hour.
Con Windows only
The editor is Windows only, no OSX or Linux versions are planned.
Con 3D features may not be enough for some users
The 3D capabilities of the engine are a bit limited (for today standards), and some of the times you'll need to work around to create something.
Con Not for beginners
Even those few tutorials don't teach you the very basics, and first you must learn the basics somewhere else (the submitted pros are by professional guys).
Con No successful/ good games
Just ask them about games made with this engine and you will see that even if you find some good games, those are mostly simple/small ones.
Con Poor performance
If you want to use more than a few actors/light/events, or you're trying to get a pretty look, you will get a significant drop in frame rates. This is especially true if you want to implement a moving light (something like a flashlight).
Con They don't fix the bugs for you quickly
If you encounter a bug or problem and report that as bug report, it will take about 1 week to get any answer, and if they solve that, the fixed version will just come up with next update for engine which that isn't be soon and no specific time, so maybe you have to wait for one month.
Con Some workflows can be confusing
Sometimes you have to do a time-consuming workaround to just do a simple function.
Con HTML5 export is poor
There are significant drops in frame rate; some bugs that can even ruin your game (also, looks like just run on firefox).
Con No IAP or Ads support
Are you a mobile developer? If so it's good to know that it has export for ios/Android but no support for IAP or Ads.
