First of all :
- I like tos kind of puzzle game.
- Mechanic is simple, but the consumable arrow is a good twist for some clever puzzle.
- Music fit the game.
- Visual are simple, and it make the board readable.
Now, what can be improved :
- I think the camera rotation is a bad idea because we don't know any-more (I mean without some thinking) in which direction the arrow we pick is gone to be.
- Movement is too slow (we already have imagine the trajectory, so it feel slow).
- Make the music loop.
- Would be good to cancel a placed arrow by simply clicking again on it (and avoid double placement)
- To avoid z-fighting, you could simply scale your arrow/final cube a bit.
- Add some more sound and juice.
Overall, nice game, it was enjoyable. Keep up the good work.
