Nice unique concept! For some reason when I saw the title I thought it was a Crossy Road clone but it's obviously nothing like it.
Some points I particularly like:
- Love the minimalist art-style, always been a big fan of simple blocks lit this way, not sure why, maybe it's that Brackeys tutorial style lol
- I like the simple animation, everything is timed quite nicely to be pretty pleasing to the eye
- Unique concept that I think has loads of options for expansion if you wanted to continue supporting it and would work easily on any platform
- Controls work great, don't feel clunky at all
- The fact that it's playable in browser is nice, I should figure out how that works myself
I think most critique I have seems to have already been said, but regardless:
- Some music might be nice, very calm minimal sort of style. But I don't think it's necessary, especially since I can see this being a good mobile game.
- Some indication of what level you're on, for the sake of tracking progress and competing with friends
- The movement charge sound is a little harsh, could be a little more subtle
- Some different obstacles like perhaps after you reach a point, the stage changes and you have to backtrack to the goal instead of always moving forward
- Not sure if this would work and you may have already tried it, I was wondering if it might look nice if the grid overlay was just on the platform and not in the empty space around it, so that you could get a clearer look at the underside of the platform when it's flipped and see the flip animation more clearly. Though I realise that the current look is likely for clarity and may fit better stylistically, but just a thought.
Hope that makes sense and is helpful in any way.
Overall, good job, you've clearly done this before hah
