This is a fantastic game from looks to mechanics. I ended up playing the downloaded version as the web version has some issues. Some notes I have are that the platforming is less fun than the Hacking puzzle parts. The jump and fall speed are a little too fast, considering all the mid air pausing and jumping toward invisible platforms. Ctrl is a little out of the way for such a frequently used mechanic and also leads to issue with pressing other keys (Ctrl+w). The last level can be cheesed by having the [creator] stand to one side when holding the button then jumping on the other red block.
Also I don't know if it was intended but, I thought that the little heart shaped plants would lead to some sort of secret.
