Super Pixel Jumper is a fast paced score based platformer with constant forward motion. As long as you avoid contact with the brighter colored blocks your score will continue to increase as will the speed of the game. Your high score is automatically saved.

The game is a port and was originally made for GP2X as an entry in the 2010 Pandora Angst Coding Competition.

RaveWild is a mix between a top-down shooter, a tower defense game and a real-time strategy. You create three different units to protect you as invaders pour in at an increasing rate. Your job is to survive as long as you can.

Changes:

* Discovered that your applications are added to the Homebrew Browser without warning. DevelopmentEffort ++
* Added some 8-bit sound effects.
* Fixed certain variables not being reset when a game is restarting.
* You can adjust the width and height gaps in the Options menu, to help with any overscan.
* Added shield element: hold either the Z or C on the nunchuk and shake to generate a unit-healing, enemy-bullet-negating barrier

Pong for Wii by thatotherdev.

Quote:

Other people have already made (what presumably must be in at least some cases better) home brew pong games for Wii. This is just another one to add to the list. Its single player only and you use the wiimote D-pad to move your paddle up and down.

It uses the same home menu as 1bit Invaders but I realized that the clock wasn’t updating (it was just sitting at whatever time it was when the game started up) so I corrected that. I also added the ability to shut off your Wii using the power button (the button on the console not the one in the menu which was already working) or holding down the wiimote power button and also the ability to restart your Wii with the restart button all of which I had forgotten to do with the stuff I put out recently.

1bit Invaders is a 2D free roaming space shooter with a fully destructible environment and retro monochrome graphics. To stay alive and gain points just shoot the circles before they reach your ship. Use the wiimote to aim, B button to shoot and the nunchuck analog stick to move.

Changes:

Everything. Similar concept but everything was redone.

Just use the wiimote D-pad to move around the screen and avoid coming in contact with the red blocks for as long as you can to set a new high score.
