The only thing that felt off was just how slow it was to get aroubnd in the early levels, then I got better with the controls.
I did find the music control, thank you, but it's just that......when it's muted, the ambient sound is there too, and I wanted to tab out for a bit, so total mute needs to be an option.
It's too bad about the design of speed, I was concerned it was going to be that way, so I was a little bit hesitant to mention it....but.....it's the only thing that kept me from fully enjoying it, and it's not even totally a problem once you get to the later levels. The early levels are the proper difficultly, they just feel like a chore to go through. XP
I haven't tried starting it up again, as i assumed it would just restart everything, but hey, if it saves my progress, then I should be fine, I'll get back to it sometime then! I do admit, I wouldn't want to have to go through those levels again, as it would be such a chore to get to the good stuff. I'm really not sure what to say about those early levels either, no simple solution exists (since the speed thing is straight out.), just a lot of tweaking? idk......wish I could help you there more though.
