I haven't seen developers making the progress incredibly slow on purpose so people would buy their in-game money made so obvious before. I do not mind grinding, in fact I think it's quite relaxing, but I actually do have to feel progress. I don't with this game, even the medium bagdes seem very far away even though I've spent quite the time on this game already. 1/5
I like the missions, physics and the feel of the game. The gap from level 16 to 17 is a bit too big. I wish the missions in level 10-16 were a bit harder. It was too easy in the beginning. Otherwise good game, you'll get my 5 stars this time.
biggest mistake you made is definitely having a seven second music loop playing again and again and again and again and again and again with no mute button.
Otherwise good game, although feels a bit slow-paced.
For people being stuck, do this: Click play game and if "ing" is not the ending then end game, when you get "ing" play and you'll most certaintly get x20 combo. (If you can't come up with 20 -ing words on the go, then you can write it down on a paper near you or something.) :)
