Cute little game :) The game mechanics is fun, great concept, but it needs a bit more polishing:
- Make the objectives clearer and more visible: I was stuck at lvl 2 because I couldn't really see the second target's requirements (the blue and yellow target)
- Maybe add trajectory line for the aiming to indicate where the barrel will go
- I think the throws lack a bit of verticality, it was quite hard to hit the yellow barrels on the wall
Overall I think it's a great game with great potential, it just requires some more improvements :D
