This game has a very subtle and calming effect on me. Despite how simple the style it is, there is something very special about its minimalism. It's definitely unique for a game at this scale, which often tends to be crowded with attention-grabbing images and effects. If you want to continue develop this minimalism as your style, it would be very cool. I would say for further development, like you mentioned in the log, adding a few more other interactive object besides just collectable or kickable obstacles, it would be interesting. Some simple music and sound effect would bring a lot too!
