Okay, I gave it a play. I really like the concept, simple and engaging. The minimal graphics are also nice.
However, it was really hard. The first three stages are super easy, then level 4 is almost impossible. I got lucky and beat it after like 20 tries, but it seemed very difficult. Maybe make some more easy or medium levels first. Level 4 should have been like level 10.
I watched an ad, the integration seemed to work well. Do you have a link to the plug-in you used? I might want to check that out.
Also, you got me thinking about making something simple and publishing it soon. I've been messing with stuff forever, but it seems all my ideas are grand and take too long to finish.
Anyhow, nice job.
