I think I've now tried every GameMaker platformer engine available and have now circled back to this one as my favourite. The "feel" of the platforming is great, but most importantly (for a beginner coder like me) it is very well commented and also includes a readme that goes into even greater depth.

One thing I've asked Slyddar for is the ability to add bigger sprites (e.g. 128x128px) which he said is coming soon. Right now it is setup for 32x32 sprites which isn't suitable for my HD game.

Other features I'd love to see that would make it the ultimate platformer engine are:

- Slopes
- Wall jump
- Roll / slide
- Ladders
- Ropes
- Breakaway platforms
- Pushable objects like crates
