Nice & neat game. But a bit too easy. The only bad thing was the level, where you had to blast the ball with the bomb. If you shoot your last blooper, the game won't wait for action. Maybe the game thinks "Missed the portal, fail!". But it should be like this: Wait until all balls are shot, give 3 to 5 seconds on wait. If no action - mark mission as lost.
In this cases, you always must have at least one blooper left. Maybe fixable. Suggestions for future-versions: A bit harder, maybe less ammo (always had at least 2 to 4 shots at the end), maybe a "hard-mode". Hope, we'll see Loopers 3 soon :).
