After reading this comment I went into the game and have listened to the feedback.
Level 1 now starts in a safe room of sorts in order for a new player to try out the controls before the venture into Hell realm itself.
Level 2 has had the players starting position realigned to face the correct direction, the original issue was cause by an engine bug when designing the level originally
Level 3 got new music and Level 4 is now added as of writing this.
There is now armour in the game too to balance out the increased enemy attack speed.
Thank you for your patience and continued support and I hope you enjoy the future update the game has to offer :)
