Lovely visuals and music, they fit very well together. Feels very solid to play. You can definitely expand this concept with power-ups and other interactions. Also, giving a hint to the player where the rocks will fall might make the game feel less frustrating. Overall, great entry!

nice idea!

i'd also recommend to adapt the screensize (does not fit on my browser window and i wondered why there is no score display... but i just did not see it)

Pleasant enough annd got  to 545 once but needs something more.
Would prefer control of the full screen as it was bigger than my browser window which meant I either couldnt see the score or saw the blocks late.
A boost may be nice and more planets
A gap between games would be nice too so you can see your score etc

I love the sound effects , art ,idea  and movement of character. 

Well done on the game!!

Love the idea

Got past 1000, same feedback as from a month ago, would be nice to have more gameplay moments baked in. All in all simple and fun, it could be a very nice mini-game to Easter egg into any future games.
