GAME: Radioactive Wastes

[komame]

Update available! - v1.04
Many changes! Many improvements!

First and foremost, touchscreen support has been added during the game. Simply touch a field, and the bulldozer will move to the designated location (if it's accessible). There is a bit of a performance issue because calculating the shortest path requires calculations in a matrix, which PPL is a bit weak at, so with longer paths, you may notice a momentary lag in the animation (during calculations). However, you can still control the bulldozer using the arrow keys, where this problem doesn't occur.
The game has been significantly optimized and now runs at 25 frames per second, but it could run much faster (35 fps shouldn't be a problem). However, increasing the frame rate beyond 25 fps wouldn't look good due to overly fast animations, so I've kept it at 25. Regardless of the platform used (G1, G2, VC), the game will run at the same speed.
To save the game state (the current level layout is saved for later continuation, previously it was only the level number), I used a "binary asset" resource, and I think this is the first program on the HP Prime that utilizes this. Thanks to this, the program and the game state are contained in one hpprgm file.
