I'm a sucker for these cannon kind of games but the video game sound effects and castle crashers music really put it over the top for me. The air spikes seem a little unfair though since they're basically impossible to avoid most of the time...
I loved the game. Although I can appreciate the attempt at creativity, I think it would have been just as good if not better with more conventional controls.
If it weren't for the elephant this game wouldn't have a badge or such a high rating. It's simply terrible and really disappointing after games like This is the only level and Achievement unlocked among many others.
Tip for level 3: stay towards the right part of the screen whenever possible. It scrolls much much faster the closer you are to the right so the distance is covered quicker.
