I couldn't progress much either :\ I can't jump to the third platform. If enemies were another color they would be much easier to see and I found the camera angle a bit narrow. I should congratulate you on the art aswell because it is delightful!
Thank you! Although it ends after the third platform, so don't feel too bad. You didn't miss anything. I think increasing the camera FOV would've made the game a lot better. I'll be working on the game further. Feedback means a lot!
