Haha thank you for playing! Project has been made open source now (since we couldn't publish on steam), so if anyone wants to add anything I'll update it here but I myself am very tired after working 4 years on it :D
Oh, 4 years. I am impressed. I haven't played for long, but I think the settings need to be expanded (I'd like to be able to turn off some of the visual effects in the game) I also noticed that blocks located on the edge of the screen are somehow displayed strangely.
