Is construct worth buying? it looks better. I tried game maker and it wasn't very good. Plus the amount of typos they had in their text make me question if they were literate.
Construct 2 is pretty good. Give it a try, you can do a lot with the free version. It has its positives (such as lower cost) and negatives (exporting to Android/iOS is possible but has a higher chance of running into problems) than Game Maker.
