This week's Ioo Web game of the week is brought to you by Freecloud, a freelance flash game developer in conjunction with kongregate.  Collider is an extremely simple yet complex physics game involving removing an object from the map, trapdoors, switches, and puzzle environments.

Each one of collider's 25 unique levels starts out with positive and negatively charged balls of goo held in a special place above the map.  Your job is to remove the balls of goo by touching a positive and negative charge together.

{sidebar id=5}{sidebar id=3}The charged balls come in different sizes and that size changes depending on the other charges are exposed to each other.  For instance, if two smaller positively charged globs of goo coming contact with each other than they will combine to form a larger ball of positively charged goo.  Vice versa with the negatively charged objects.

When objects that are of different charges contact each other, an explosion occurs and equal amounts of both six are removed from the game.  Adversely, if a smaller positively charged object touches a larger negatively charged object, the result is that some of the larger object will remain.

The trick is to get the positive and negative charges to come together in equal amounts.  Sounds simple doesn't it?  Well, the real fun ensues when the game begins to introduce winding slides, trapdoors, bouncy walls, and neutral charged objects.

Game accessibility

The simplicity of this game makes it extremely accessible.  In fact, AbleGamers' Mark Barlet called this game "extremely AbleGamer friendly."  Let's explore why that is.

First, the game is controlled completely by the mouse, thus one-handed gamers and mobility impaired gamers will be able to handle this game just fine.  There is no time limit and you get as many do owners as you need to complete a level.  Combined with an auto save feature, so that you may return to the game at any time, disabled gamers will have no problem with speed.

Deaf gamers and hearing-impaired will be able to fully enjoy this game because there is no sound other than ambient background noise.  Everything is explained fully in text, with shortcuts and clickable objects, leaving no need for sound.

There are colors in this game but everything is clearly marked with either a plus, a minus, or a solid color meaning neutral.  Colorblind gamers should have no problems.  The one sticky area maybe the line between where objects are placeable and not but you can see the difference is even slightly between black and green, you should have no problems.

I found this game to be extremely accessible and a fantastic physics game.  If you love physics games and/or puzzles, this is a great casual game.  Unfortunately, the creator of this title has not yet responded for a request for comment, we will keep you updated.
