I saw restart option. I meant I played it on my phone and closed it to go and do some stuff, so when I launched it back I had to start from the beginning
Found one bug: if you slam one of the colored switches and reset the stage, the gates will keep their condition from before the reset. I had to save, reset cart and load to get everything back to normal.
Looks like ice blocks were also bugged. For now during reset they leave those blue squares but still keep previous melted condition so you can pass through.
