I'm sure most of us have a collection of half finished (or even less) games. Show us what you're sitting on!
Here are mine (in no order)
Shooter
This was a space invaders like game I started some time back, the things I liked about it was that you could fire too much and overheat your gun, also the top level of enemies have a nasty weapon waiting if you clear the line to them.
Fuzerk
My tribute to one of the best arcade games of the early 80s, Berzerk! I never did finish it as I had a weird and rather rare bug I never did track down.
Bubble Bounce
A simple puzzle/shooter where you have to bounce to change the colour of the tiles and match the entire row to the target colour and then a new row is added, you also duck to avoid enemies or fire soap suds at them if you have enough
Bubbles
Simple puzzle game where you hold the button down to bounce higher and try to collect the colours shown
Moonbase
Another arcade tribute, this time Missile Command
got quite far with this but it was never completed.
Star Castle
Yet another arcade tribute, this time Star Castle (or Stellar Castle as it was known in some places) Sadly a bug with the enemy sparks killed this game off.
Fuzitar
Yep, arcade again and this time a game based on the superb Gravitar game. Managed to get to switch levels but for some reason I stopped work on it.
Crazy Bubble
Yes I'm also seeing some obsession with bubbles here.. weird, but this was going to be a game like Crazy Balloon but as you can see I didn't get far and it wasn't very good anyway
Laser Blast
A copy of one of my favourite Atari 2600 games, Laser Blast by Activision. This was pretty much 90% complete but was never finished.
Heli Scramble
Based on the classic Scramble game. I didn't get very far with this because doing all the 100's of tiny collision shapes for the map in the map editor was a bit of a nightmare so I dropped it.
UFO rescue
This was going to be a wraparound game like Defender, you can see I got the radar/minimap working great but actually coding the "wraparound" even with help I couldn't manage it and the game was dropped
Cops
an old game that I was working on before the last patch (you can see the patch kind of messed up the sprites and collision boxes) The idea was to run around and knock the coins to the bottom and get away from the cops. I was abandoned due to lack of interest.
Now I've shown you my embarrassments, you show me yours?
