You should mention the controls in the description box or something similar.

The game is too fast paced for there to be a time limit before you can use an item again, you should've made it so it automatically appears without delay
nice art and decent sfx. put controls in description as they are not obvious. Shame you can't destroy elements if they are not connected to the base as in similar games in this genre.
