Radioactive Wastes [UPDATE 2023-11-18 - v1.04]

[komame]

I just did a small update.
Unfortunately, I can not fix performance problems on some levels, the HP Prime is a little too slow.
Without access to the native programming I can not have the speed, but today I introduced some changes that reduced the sensibility slow down (I am reducing the frame rate when calculating logic takes too long).

Edit:
The problem occurs only when a button is pressed (and held). I wonder if instead use of keyboard I could use the touch screen. Then the problem probably does not occur. Besides, I could implement the shortest path algorithm and a bulldozer could reach the touched field automatically using the shortest possible route.
