Reminds me of spending hours upon hours on Chip's Challenge. Unfortunately this doesn't seem mobile friendly.
Have you ever tried Chip's Challenge 2? Chuck finally got the rights back and released it recently[1]. I actually thought the second one had even more interesting computer-themed mechanics than the first one, it's a shame it was released so late. There's also a nostalgic tileset you can drop in for CC2 (depending on which version you consider nostalgic)[2].
