It's good:)

the idea is cool. but an annoying idiot following through the videos. instead add the challenges in the levels. Also it only takes up a quarter if the screen and you don't do anything clever with it.

It's alright I guess.

At first I thought what is this crap, the art looks poop
and the game play very basic.
But then I got the idea and it is super original, just the execution is lacking.

You play a youtube channel that has to get subscribers.
- Then you have to face various struggles that youtubers face, such as stopped channel

Improvement points:
1. In the level with stop the block. Instead of leading the block to the next level, what if you actually had to stop the block!? For example you could make the level so that you could push certain blocks to prevent the block from reaching your channel and then when it couldn't walk any more path, you won!
2. No need to press space to collect to subscriptions, they are like coins right? You want to collect all of them. Do you press space to collect coins?
3. Make it possible to walk a direction while holding the key for another direction. I found myself getting stuck often for example I walked right, then I had to go up, but I was naturally still holding right down.Then I had to unclick right before I could move. This felt frustrating

Not too bad, but there is no actual ending, not to offend but you should check when you write, just a suggestion, i'm not hatin'. Other than that, I actually like the idea! Good job!
