I had a lot of fun with this! Playing on Mac so I had to play in browser, but the performance felt alright. I thought the premise was interesting (basically Inception), and the voice acting was really cool to hear, if a bit ridiculous (the scientist reminded me of Rick from Rick and Morty lol). Gameplay was also quite fun, basically just a simple FPS. Moving around made it easy to run away from enemies and kill them, though I ended up stopping at the 3rd level, when you re-fight the necromancer, just cause it got tiring running around in circles, so maybe enemy health could be lowered/bullets could be stronger so fights don't end up going on forever.
I thought this was a really fun entry overall, so great job!
