Hey, currently busy with other things, haven't been able to continue work on this for now.
This should be fixed now, sorry about that!
Noted, the progression system hasn't been implemented yet, but should be out in the next update.Thanks for feedback and for playing!
Fun demo! Looking forward the next update.
Small issue when rewinding time while the Boss is teleporting, he'll be invisible while attacking until he uses his teleport again.
This was a lot of fun! Could you add a toggle for screenshake? It gets a little nauseating once you reach higher fire rates.
