Interesting concept, combining a Deckbuilder and an RPG. I would have given some way to remove cards, and make more enemies do something like the Artist's Block the final boss can do where they mess with your cards.
Whoops, I did my math wrong on your height. I forgot that I divided by 11 to get your width. Being about twice as tall as you are wide, you are 109015439.273 meters tall, which, while giant, is not near the width of the tower itself.
The final upgrade says "Your boots are already faster than their own shadows". In order for this to be true, you must be moving faster than the Speed of Light. At the highest boots upgrade, it takes two seconds to move from one side of the tower to the other. In one second, light moves 299,792,458 meters (source: Yahoo Answers). This means that the tower is 599,584,961 meters wide. The screen is 11 Knight Widths long. Your character is 54507719.6364 meters wide. He is about twice as tall as he is wide, making him the same height as the tower is wide. You are a giant and this tower is even bigger.
Dev1: Hey, let's make Buritto Bison, but in an office!"
Dev2: Okay, but let's strip out all the character and originality, and make a generic launch game!
And so they made My Dear Boss. A solid game that's in serious need of some ability to actually make an impression on you.
I was expecting Danmaku, but maybe that's just from playing on Easy first. Either way, the game is very fun, slightly challenging even on easy, and I was always kept wondering how the boss was going to attack next. 5/5.
