Crap when you're doing endless, with full upgrades, max lives, max bombs, and your kinda good at this, and on round 30, you start to feel like you're wasting your life. :/ Still fun!
I'm sorry boss, but as I was just about to finish my blueprints for the city, a Bicycle just appeared randomly and was doing circles around these spinning "Checkpoints" and it was just making red, blue, and some purple lines all over the blueprints. There was also a Label saying Fig. S and then Points, and it would show a bunch of numbers just increasing by the second. The strange thing was that when the "Bike" would hit a line of my blueprints, it would fall, and disappear. Then it automatically appeared at the last "Checkpoint" and just kept going. I still don't know why this happened. Do you know why, boss?
I like the game because it doesn't have any trophies or achievements (not including the badges which you can get easily) or upgrades that you would want. Plus its a simple concept, addicting, and definitely worth 5/5.

I've thought about a "custom mode" myself once, but I'm curious about what exactly you mean by that. Can you elaborate ? :)
