Yes of course...its really easy...I suggest using the 8-Dir Behaviour and then put physical limits on the edges of your world space where needed...
Basically what you are looking at is a isometric type control...(search the forums for that , there are plenty of good Tutorials on that kind of thing..)
Also look into the Platform Jump with 8-DIR..it works if you tinker with the controls for a little or simply use a more simple Graphical based jumping system...using images only not in game mechanics...
Many people have made stuff like this...its quite easy..once you know how..If you get familiar with the basics of Construct 2, what you want to should make sense in no time at all
