I enjoyed the game, I got to the end. The recall mechanic was nice, I'm interested to see how you did it to be honest, so might check the code out.
Feedback:
- I had no issues solving the puzzles, they were well laid out and pretty self explanatory. Wish there was more though ^.^
- When I first started playing I didn't know what was expected, I pressed esc and noticed a "recall" thing I pressed it because I didnt know what it was, and then caught on to the game. I think you should either: have a how to on the main menu since this is the first entry point to the game that mentions what recall *does* (as well as in game)
- On the last puzzle when you press the trigger, the paids that come out don't come out smoothly they kind of jitter, which looks adnormal and throws out time causing me to fall even when I tried to anticipate it. I eventually got to the end but those 4 floating squares need movement smoothing.
All in all, great game idea! :D
