Update: Just finished the rest of the game. Those later puzzles have very clever solutions that I really enjoyed figuring out.
I just have a few final notes about the game now that I've finished:
- It would be nice to have an undo button that let me rewind a couple moves, because I often found myself doing one wrong move or two that would make me restart the whole level. It never took me too long to get back to where I was at, but it would also be nice to not have to re-setup my entire solution again.
- I still really do like the musical aspect of this when inputting the "F"s and "O"s, but sometimes hearing it in quick succession it sounded a bit harsh over and over again just because of the nature of the music and the instrument. This is a small gripe, but something I still wanted to point out.
- I ran into one small bug where I was able to walk off the playable area on one of the last levels. I didn't use this to exploit the level, but it's just something I discovered and wanted to let you know.
- For me at least, I often got my directions mixed up when turning the characters. Although the little diagram with the controls was helpful, sometimes figuring out the orientation was a bit confusing and I would end up just turning right 3 times instead of left once (and vice versa). Maybe some more detailed display for these controls could be helpful.
These items are not to detract from the product you've made, of course, but just little things I wanted to point out because I would really love for this game to be a fully released game on steam one day. I really did enjoy it, and the ending was quite nice and i could see that possibly expanding future puzzles. Again, I really loved the game, please do keep up the great work!
