I’ve made a java game played in an applet a few years ago, and have recently been able to make a version of it for mobile phones.
It is a freeware maze-puzzle game, called Otto’s Obstacles.
Here is the link:
Enjoy 
I like it! Reminds me of Chip’s Challenge, and based on the name, I’m assuming that’s where you got the inspiration. =)
I found the first level entertaining, but i have no idea how to beat the second level, so I got frustrated and quit.
Yes I know of Chip’s Challenge as well
The first level is just to get the hang of it. Second level and following levels are more challenging. There is a walkthrough that describes how to beat the first 11 levels on the page though.
update
I’ve made 5 levels after level 1 that should be rather easy to solve.
I like this genre! I think there was something on the BBC micro called repton which was quite similar.
Unfortunately the applet seems to get into a state where each time I press a cursor key the move counter goes down but the character does not move.

Hi josh
Thank you for your feedback
I’ve been working on adding recorded solves for the game, which may have caused the problem. Also recently I applied double-buffering which should make the screen run without flickering. I still need to work on some timing issues. I am testing it on 3 different computers to see if it works by different speeds. Also I am looking into your problem which I haven’t encountered. If the problem you told of still arise I would be grateful if you could email me at the email shown on my webpage.
Regards, René
The “help” window doesn’t take into account font metrics, so all of the lines are clipped. There’s no scroll bar, so I can’t read all of the text.
Level 2 appears to be impossible. The solver just keeps dying. I don’t see the walkthrough you mention earlier in this thread.
I’ve now fixed the help window so it takes font metrics in accont. There was a big issue with the solver, causing him only to work some times. It should now have been fixed. The walkthrough has been removed, the idea being that the recorded solves should help with solving the level.

Nope, I still can’t move
What java version, operating system and browser are you using? It works well in my Win XP with IE 8 or Firefox 3. If you have clicked outside the game you can click on the screen to bring it into focus.
Win XP, Java 1.6.0_05, Firefox 2.0.0

It works for me in IE 6.0, just not firefox 2.

I’m having some trouble with teleports, they don’t always work and therefore I get stuck.
Yes, I have also noticed the same thing with teleports.
The teleport seems to work depending on the side you enter it (in the direction you want to teleport?).
As Tobiking says, the teleporters will only teleport you to another teleporter if there is another one present in the direction you entered it. If you enter it and there is not, it will just disappear. I will try and make this better explained in the help text.
I’ve installed Firefox 2.0.0.20 with java 1.6.0_05 on another Win XP pc, and it works well, so I can’t see what could possibly cause the problem with not being able to move? Perhaps it’s the keyboard driver or something else. Hard to figure out.
update I’ve made the game so it is in focus all the time except when the Help window is open. This should help with the Firefox issues. Also I’ve made a sound for the disappearing teleporter (if there is only one) and explained this better in the Help window.
