Cool mechanic! I like that your metal rock is your weapon but also one of the failure conditions of the level, interesting dynamic. But the random movement of the target makes the levels quite frustrating, I think it would help, if they followed a preset path.

I actually have a post jam version which addresses this issue, because I just couldn't stand people telling me that the game is fun, but it is frustrating because of random movement. Note: Do NOT rate the game according to how the game was in Post-jam update. That can get my entry disqualified. If you want you can check it from my profile
