Thanks! I'll try your game once I'm back from holidays in a few days.
I'm sorry you couldn't reload.. After the voting period ends, I will release an update with game saves, a pause/unpause feature + a restart current level button probably. For now, if game freezes you can't restart a level. You have to restart the game and loose your progression.. I'm sorry about that.. I didn't got enough time to work on save game feature.
