This game is fantastic! The concept is super clever and very well executed, and I loved the adorable-yet-macabre suicidal robot. The level design is good too; they present interesting challenges and explore the mechanics well. The sections where you had to do a leap of faith to get a battery just out of range were particularly satisfying. Don't be too hard on yourself about the length; you only had 48 hours, after all, and what's here is great. I'd love to see more!
