Wait! Hold on! I managed to save them all :D That goes a bit against the theme :)
The graphics were really pretty! You notice the style from the start, and the gameplay elements are instantly recognizable.
The sound was ok, but some background music would enhance the experience. There are some sites with cc0 license music. For example music on mobygratis.com would be free for jam project like yours.
The gameplay was fun, but it felt like just the start. If this was a first level of a longer game that would be great- I can see a ton of potential in "sticking tiny dudes together" mechanic, especially when you introduce some complications :) As it is, it leaves you wanting more.
Over all- great graphics, fun idea, lots of potential! Keep it up!
