Good game! I really like the story setup & the pixel art. The controls felt smooth and simple. The game reminds of the more realistic and difficult platformers (Oddworld, Prince of Persia). There are a generous number of checkpoints which is appreciated. I wasn't able to figure out how to progress much beyond the first upgrade. It seems like you have to back track, but I couldn't figure out where to go. One balance suggestion I have is increasing the platform size, as they felt cramped due to enemy placements.
