Unique level generated every time you play :)
You cannot lose this game, you will always reach the finish line, but how quickly you get there depends on your skill! Ideal game for young children, or in my case a 'grownup' who's not all that grown up and likes to kill time playing silly phone games :)
If your child loves car games, or you love retro 80s and 90s games, you should definitely try this!
Making this basic car game was a personal learning exercise for me. I kept it simple enough to ensure I could actually get something to a finished enough state that it could be uploaded to Google Play. The lessons I have learnt will allow me to go on and work on a more ambitious project next time - maybe a mario style platform game, maybe a less casual racing game, maybe a doom style first person shooter, or maybe another casual time killing game, I don't know yet...
If you are interested in making your own games, and would like to read about the process I went through, I published a worklog here - http://theinvader360.blogspot.co.uk.
If you think the graphics/sound/music/whatever needs improving, and you have skills in that area, you are welcome to get in touch and submit improvements that I could include in future updates - that would be so much nicer than just complaining and leaving a one star review :)

This simple sensory app came about as my daughter was very interested in testing my latest game (Jewel Match Blitz - https://play.google.com/store/apps/details?id=com.theinvader360.jewel.match.blitz.game.free.android). She sure loves grabbing my nexus tablet and tapping the screen! :) The downside is once the game ends it no longer responds to her tapping. I decided this was the perfect opportunity to make a little standalone app that is suitable for her to play with.
I read up a little on sensory applications and how they can be beneficial for children and adults with special educational needs (SEN), learning difficulties, and certain disabilities. Conditions such as autism and impaired vision (blind) are especially well suited to interactions with a simple cause and effect app such as this one. I not only wanted to share the source for the benefit of other developers, but to also publish the app for free on google play in the hopes that someone in need might also benefit from it.
This app is totally free, and is ad-free. If you would like to show your support please just leave a rating/review and consider checking out my other apps :)
This small, open source (https://github.com/TheInvader360/sensory), free, and ad free application demonstrates how particle effects can be implemented in LibGdx.
* Touch the screen to trigger a particle effect
* Keep touching to spawn more particles (new particle effects triggered every 0.2 seconds)
* Multitouch enabled, touch up to 10 points at once to spawn from multiple touchpoints simultaneously
Android software buttons are hidden in an effort to minimise accidental app closure. Tap the unobtrusive close (x) button to close the play screen, then tap the quit button on the menu screen to quit the app.
There are three main target audiences:
* Developers interested in LibGdx - this project touches on things like particle effects, object pooling, multitouch, screen transitions, asset management, etc.
* Babies - my daughter is 9 months old and she loves playing with this app. A little time spent interacting with this app should help improve her hand-eye coordination. I've also noticed a definite look of accomplishment on her face when she realises that by touching the screen she causes the lights to appear and sound to play.
* Children and adults with certain learning disabilites or special education needs - some can benefit from interacting with simple sensory cause-and-effect apps like this one.
The game is very easy to play - simply tap to shoot. Hit the minimum amount of ducks or more per level to progress (check the arrow on the duck counter display). There's a nice bonus if you manage to shoot all ten ducks! Don't get too trigger happy though, you only have a limited amount of ammunition...
Easy to start with, gets harder over time. Perfect game for making coffee breaks fun, and suitable for children and adults of all ages - this game is for everyone! Simple addicting casual fun :) Anyone can go on a duck hunt, but it takes skill to unlock all the achievements!
Share your duck hunting highscores with friends on facebook!
Compete against hunters worldwide on the global highscore leaderboard!
Add friends to your friend list and compete against them on the friends highscore leaderboard!
