I am one of those people that like to delay things until the very end. From college assignments to test preparations and even submitting articles to Jon, I tend to do them on the last day. And this is where I get a lesson from Ra2 - don't delay. Act brilliantly and remain ahead of time before it outpaces you.
In essence, Ra2 is an extraordinarily simple game and a simple concept, but it forces you to challenge yourself to get better and better at each level. It's the sequel to Radium, an action puzzle game in which players have to navigate a ball through a maze using a pair of tractor beams located on the sides of the screen. Activate the right tractor and it will pull the ball right for example, and you must use a combination of these in an increasingly complex manner to navigate the environments. The aim is to try to complete the levels in the quickest time possible. If you don't complete it in the minimum time, well, it'll eventually block your progress towards the higher levels until you get the required amount of radiation.
There are a variety of levels with many situations and it requires a degree of strategy to control the tractor beams to guide the ball through the maze in the minimum amount of time. It can also be remarkably difficult, so be prepared to fail hard on your first goes.
Games likes Radium, in my opinion, are pretty useful when you have a shorter time span for gaming, or like to do gaming in intervals, because it's like gaming fast food. The game is divided into sectors and you can either play the most difficult part of the sector first or perhaps the easiest one based on your mood at that time. You could finish multiple levels at once or just spend the time trying to get a good score on one level.
It's proactive because it forces a player to go through a level a certain number of times in order to complete it quickly and beat their own high scores and, unless you're familiar with premise, you'll find yourself going over and over these levels and perhaps even slapping your head on the keyboard in frustration, staring wide-eyed at the progress of your Steam friends, which inculcates a sense of competition and the desire to get better.
Radium 2 is simple to the core and adopts the approach of games which you often encounter on mobile. The likes of Angry Birds and Plants vs Zombies form the bedrock of this platform, yet Ra2 manages to add its own spin in the typical mobile pick-up-and-play game for those who are looking to keep themselves occupied while listening to their playlists. Because in essence you don't lose in Radium on most levels. You may end up completing the level really late but hey, you have completed it. There is no fail state and you can always jump back in later for a better score.
Talking about playlists, I reckon you're going to need some extra music because Ra2's collection of tracks felt really dull to me, and games like these should have a bigger collection of music in my opinion because it can keep the gamer more engaged. But then again, the problem can be solved by your own music playlist.
Anyway, as I said earlier, better scores are required to progress, as higher levels will need more counts of radiation (scoring system) in order for you to progress further. With that being said, Radium 2 definitely has a lot of replayability since players will find themselves going back in again to get the high scores, and the game has around 130 levels. It's also to while away hours having fun with a relaxing side-scroller which is easy in theory but challenging in practice.
For something so simple it's very hard to find a con in this game. The only thing that can be frustrating is getting the high scores. For a newbie like me, I have rarely managed to break into the top 50 leaderboards. But then again, it's not definitely something that can really lower the score of a game in this particular genre.
So to sum up Radium, it's a fairly good physics game which has all the qualities to keep the player occupied for hours on end, striving desperately to clinch the top awards. There's nothing really wrong with it, thius neat little game doing exactly what it set out to do. It speaks well of the efforts of an indie developer who has turned out a gem in a minimalist fashion.
