Neat game. I liked the simplicity of the concept.
I liked some levels, but not others. What put me off is maybe the level design. For some levels it became a game of precision maneuvering the launch. In some levels like Level 6 with the moving obstacles, I still have no idea how to clear it. I keep trying and something works. In level 7 there is a solution where you shoot to the lower left, and the moving obstacles become redundant. Same with level 8.
The levels with the traps are better I guess. They make trial and error more costly, so it encourages more thinking. Moving obstacles were difficult to reason with.
Overall the game has good potential, with room for improvement in adding more mechanics and level design. All the best!
