So, not a bad game - I can see why this is clone exists (and, the fact that it's a clone of a clone is a reason I couldn't give it a full five stars...I choose to reward creativity as that final star.)
While the 'level' design isn't horrible for helicopter-game standards, my main gripe is how the hitbox for the characters does not fit the character itself; it's about half the size of the character. While it feels good, it's visually disconcerting and adds an unnecessary level of guesswork to an already challenging game.
Also, the character's extremely pixelated look contrasts rather sharply with the smooth vector backgrounds. If the character were more smooth the visual style would actually be way more pleasing.
The game's soundtrack is simple, and dosen't get in the way which is nice, but it also dosen't sound like it really fits this game; it dosen't add to the frustration, it dosen't add a sense of wonder...it just adds a sense of, 'WTF couldn't they find a better composer?'
All in all, not bad. It could be worse (by which I mean a cow clicker.) But, a little more love could make this clone of a clone of countless other clones stand out and be a much more enjoyable game. 2.5/5 - and I look forward to what is done with this next. :)
