Spectraball is told to be a puzzle and platformer game. While the platformer part may be right, it is not a real puzzle game as thinking is not required. The so-called puzzles are way too linear and obvious to be a challenge and the only hard thing is beating your own timerecord, which shouldn't be the case for a puzzle game.
The graphics may have a rather good quality compared to other games of the genre, but there are a ton of useless and not good-looking shaders that make the game look even more unrealistic than it already is because of the platforms hanging free in the air (which is of course needed to qualify the game as a platformer, the devs may think) An example of the shaders that were put in the game without thinking can be seen in the screenshots: Every surface reflects the magic shine of the ball, may it be stone, dirt or snow.
The level-design is done very poorly and broken. The major problems include but are not limited to: Way too easy and boring parts, shadows hiding passages that don't seem to be meant as a secret passage (It would make no sense to hide it), and most importantly: About 50% of the obstacles are easy to overcome by just speeding towards them and then jumping all over the puzzle, skipping the complete part that would of course not have been a challenge otherwise.
The gameplay is way too short. I was able to complete the whole game in only 2 [Edit: 3] hours of gameplay. I did not try to be as fast as I can and instead tried to have fun with the whole world, but there are no extra parts or passages in it, only the straight obvious ways the player needs to take. I also played many levels multiple times because I got tired of this game when I first tried it and then decided to play it completely several months later.
I definetely do not recommend the game. Only 2 [Edit: 3] hours of gameplay are not worth the price and I did not enjoy any level of it and would not even have bought it if it was on sale for 20% of the full price if I knew that before.
I remember playing Ballance on my old computer, if anybody knows that. It is not as fast as Spectraball but sure has its similarities, being a true puzzling and platforming game. Why don't you have a look at that instead?
