Cool little scrolling shooter!
I like how you integrated a hacking puzzle to hide certain paths. Although controlling both whale and hacking cursor at the same time under the pressure of timer led me to many dashes straight to the wall ¦3
The final boss felt easier than normal enemies, you can try upgrading him a little bit and adding the hacking element to that fight after the jam.
Nice attempt into pixel art. Music and sounds fit nicely to it.
Unfortunately, final cutscenes didn't work well on my Linux. Most of the times the screen was filled with solid background color, with some alternating frames of actual scene barely coming through.
