Honestly very impressive for a 1 hour project, nice job!! Would love to see what you could do with 2 hours :) The minimalist graphics work very nicely and the soft background music fits well with the overall vibe. Having the controls inverted was a fun little challenge at first but after a couple of levels it gets way too easy way too fast. I made it to level 20 before I got bored and stopped. I think you have an interesting base of a game here and if you added some variety to the levels with obstacles, enemies, etc it could be a really fun experience. That being said I think you did a great job making something in just one hour, keep it up!
