Wow!
The presentation on this game is amazing! It's just a great example of how adding a bunch of small additions to the look of a game makes for so much. Things like the subtle gradient beneath the tiles, or the fade in / fade out transitions of the tiles. Everything lighting up when you start, its great!
The audio is also very good, its maybe a little bit repetitive with the one high note being very recognizable, which can make it feel more repetitive than it really is.
Great into to mechanics, making the player push the box to get to the level is a great way of showing what something does with no text. As well as the later arrow platforms being easily guessed as to what they do.
The main menu screen has a really cool selection idea, with moving around the screen itself. But, it was unintuitive when first starting, as I thought the menu was broken since I couldn't click on them.
Being able to undo on a game like this feels amazing, since it normally sucks to have to redo an entire sequence on actions on various box pushing / sequence building puzzles, especially trying to remember what you did. This game is very un-punishing, and I like that a lot.
One downside I noticed is when the (Robot)? is dancing, its beat feels just off of the music beat, which can be unsatisfying for when your trying to jam out to the movements. :)
Nice job!
