Bothersome
By all intents and purposes this looks good on paper. However, you broke the cardinal rule of gaming; difficult controls doesn't make a challenge, rather it makes tedium.
The graphics are perfectly fine, the concept is fun yet simple, and the controls are the only thing this game has that's original.
This is why the game gets a 4 and not a 6 or 7 which I would give it were the controls better. I see what you were trying to do, making the controls not super fluid so the game isn't just a walk in the park, but the build-up of inertia is spontaneous, rather than logically gradual. We're all humans, and we've all lived with basic physics influencing us, so it's kind've hard to break the notion
That's just part 1 of the controls, the 2nd part is that it's stiff. By stiff, I mean it's like my keyboard is dipped in syrup during gameplay. There's a slight delay between push and action, then the lack of gradual speed buildup, it all just adds to make this below mediocrity.
Maybe next time,
