Pretty good game, I like it.
The Good
Graphics - Character and area models are great. I do also like how that despite there only being three areas, they can be set at different times of day.
Challenge - It really feels like a game of reflexes, especially when you hit the 50k mark. Running fast is super fun, though I wish there was an option to begin your runs faster.
Power Ups - Most of the power ups are all powerful and affect the game in some way. Pretty cool sound effects to go with them too.
Replay Value - 7 unlockable characters, loads of character upgrades, a career and rank system, and competitive high score? That's some serious replay value.
The Bad
Music - The main theme isn't a bad song... it's just that it gets repetitive in a game like this that you play for a quite a while. Perhaps add a menu theme, Lucky Cat theme, stuff like this would be awesome.
Characters - The characters really are only aesthetic changes. Giving them unique attributes would be great.
The challenge for me was fairly odd. I'm not too sure what to make of it. The physics feel really strange to me and I can't get around the momentum. In the last level I didn't feel like I was getting any better, I just suddenly won. Yet I feel that the momentum is supposed to be part of the challenge, so going by that... nice game, but it's probably not for me. 3/5 from me. :)
Finished with 505 deaths. Now I'm done inflating my head to the point where I can't fit through doors, I'd like to say this game was pretty awesome for the most part, especially the last few levels. The ones between 25 and 35... around that anyway, just felt like trial and error, and just a case of run forward and hope you pressed jump at the right time. The last few definitely demanded a lot of skill and memorisation. They were "easier" but not in the way you'd expect than the aforementioned levels. They felt like they were challenging your skill, and not your patience. Thanks for the fun times though, 4/5 from me. :)
Awesome game from beginning to end. Nice original graphics and the music tracks were nice and I like the variety of characters. And it really was challenging, even if I thought the Immortal Pharaoh was harder than the final boss. :P
And it just so happens that only now I find out about the cheat menu, after dying constantly. Still, awesome game, can't wait for the sequel. :)
