Heyo!
I want to keep it short to spare you some time:
Last level is too difficult. I think I cheesed it by throwing my magnet under the block so when it fell back down it blocked the button. I would like to move around while aiming to be more accurate and to speed up the gameplay.
I would like some visual feedback for how long I need to hold to reset the level.
Even though I have 7 keys, the hub says I have 6.
I loved the way the puzzles work, sometimes the gates felt useless. learning curve is good although last level is bit too much. The Hub feels alright, but something feels missing / wrong, but I can't put my finger on it.
Keep up the good work!
