This game is now complete and available for download. A lot of improvements have been made since the demo. Any additional feedback would be greatly appreciated

I uploaded an updated version which should hopefully fix all of the inconveniences reported thus far.

I made the dialog text scroll faster, and now the dialog box moves with the main game window.
If you want to view the dialog/instructions again, I made a mission log you can access by pressing the R key in-game.

I also made the movement controls smoother. If you let go of a movement key and are still holding down a key, the key you're currently holding down will now register with the game.

Also, I fixed some spelling errors in the tutorial...

Give it a try and see if these are decent solutions to those problems.

About 4 months ago, I released a game called Intruder's Thunder. Before I released it, I had a prototype version that utilized a scrolling background. I kept working on it, adding features, optimizing a lot of the old (bad) code, reducing the number of threads used, until I felt like I had enough for a demo. It even comes with an unrefined, quirky level editor. I would really appreciate any feedback anyone has on my game.


Update 1/11/13: The game is now finished and is available for download here:

Thanks! I made the development mistake of not making a level editor, so making each sub-level was a pain. I actually construct each sub-level using for() loops to place sets of tiles on the map (I don't recommend this approach to anyone). It was a pain to test, and took me longer to make the levels than it should have.

The levels generally get more difficult as you progress. If anyone ever reaches the final boss, the fight should prove to be at least somewhat challenging. Perhaps in a future version I'll triple the width of the guard's vision, and maybe extend the length by a tile or two.

You'd be better off only using keyboard input to control the game. A mouse would be hard to use to control a frog. If you remove the mouse listener and stick with only the key listener, this will go away. I don't know much about the mouseDragged method; I've never used it. If you really want to use the mouse, I think the LWJGL might have the capability you're looking for.

It was somewhat unintentional that the level-skipping was put in. Originally, I planned on having a save game option but decided that it wasn't worth the hassle. So I decided to have a level selector. Well, I was too lazy to put that in my game, so I decided to just allow players to skip levels .

What do you guys think of a potential sequel to this game with a scrolling background, different weapons, and a level editor?

If you google "java frogger" this is the first thing that comes up: http://www.reinhardtfamily.com/Paul/Frogger/

I think a game like Frogger is a great game to start out with.

An easy way to implement the game timer is with a Thread. You can have it sleep for, say, 1000 ms (1 second) and decrement a counter variable until it hits 0.

To disable the mouseDragged method, just leave its body blank.

For your game mechanics, I'd make some sort of collection (probably an ArrayList) of cars and logs, give each car/log their own direction variable (Enumerations are great for this) and speed. For collision detection, the game is simple enough that you can have all obstacles check to see if they hit the frog every time they move. I hope this helps.

I had the pistol start with 0 bullets on purpose (I thought the game was too easy; I'm probably biased since I made it  ). There is an ammo pack for it in a room if you head east from the entrance. If you get fed up with a level, you can always skip it. The guards all move on predetermined paths until you get spotted, so you should be able to slip past them unnoticed in most places. I'm glad you like my sprites! Thank you for trying my game. I hope it's entertaining.

Intruder's Thunder is a 2D, Tile-Based game in which the player must navigate various levels while avoiding enemy guards.   If the player is spotted, he will be fired upon by the guard that spotted the player.   The guard will then pursue the player relentlessly, until the guard dies or the player dies.  It features a story, 7 levels, 3 boss fights, 4 different weapons, and a fitting soundtrack.

This is the first big game I have ever made. It's not perfect, but it is fun. Any feedback would be greatly appreciated!
