It's a good - but super short - game. 2 bits colors are doing great so far, and I like destroying those robots!
I feel player controls must be reviewed because they're a bit fast and the jump is a bit weak. Also if you spam the jump key, you'll get a sound anytime you press the key even if the jump isn't ready (that's a small detail but, heh).
Not sure the explosive blocks are that fun tho, in hard mode it's slowing you down by a lot. I mean, they're super easy to avoid but are simply "annoying". I liked the way you can build up your own path with the boxes but the fact that they destroy it often felt a bit rude.
