Hey I came over to see what game you had made :D Thank you for rating ours and giving some feedback!
I love your game, you are right it is quite similar to what we did, yours has great music and I love the graphic style of the pixel art but feel it lacks some contrast of the PC on the background, minor nit pick.
Mechanic wise I love how simple the controls are but some of the collision detection is iffy, i was getting stuck in some places especially doorways, or get nudged to a different place. I like that you included pick up batteries to extend your battery life, we should have incorporated something like that!
Overall a very fun and quirky game, the music is very thematic and atmospheric. Will play again!
