Hey, thanks for playing!
Glad you like the assets and ideas! :D (I still gotta polish it up a bit more.)
Oh, I totally forgot to add that in the description when updating the description! (Good catch!)
I just updated the description - you can toggle the relics Tina can equip by pressing the "U" keyboard key (you can cycle between a "halo", "shield" or "wings" relics that passively help out the player)
Also, if you press the "1" and "2" debugging buttons, make sure you are in one of the four levels outside of the main HUB world (where you initially spawn) - the debugging only works on the outside levels. ;)
