Overall it is a nice game. It is just a Cuphead ripoff, but it looks fine and is kinda dope for 1 week.
Things i would improve:
-Feedback for the player (When you get hit, When you hit, Arrows when an enemy is out of view...). This one is actually the main problem of this game, and the one that made it kinda frustrating.
-Main menu is too simple, the font is blury (you need to scale font size, not the font gameobject, so it doesnt miss the clarity), and the Exit button doesn't work, at least for me.
-Audio for shooting, enemy attacks, jump, pressing buttons... The music is really nice and really suits this game, congrats to ur producer friend.
-Change the build name to something that isn't Oblivion lol.
-Improve the overall UI, it looks really rushed i guess cause of Gamejam time.
-Some minor bugs that need to be fixed (Animations, not being able to shoot backwards if you are walking...)
-A pause menu.
Thats pretty much it, of course it also needs polish, but for a 1 week game, it is pretty dope. Good job!
