Great game!
The controllers felt very smooth and pretty easy to get used to, as well as the upgrades, and the art and sound design all conveyed the atmosphere excellently.
I think the only criticism I would add would be that it felt really easy to get lost specially on the upper areas of the map, I found myself walking in circles for a long time before finding the attack upgrade. But this seems like it's been pointed out by quite a few other comments already though, so I have nothing to add on that I think. I feel you, deadlines are merciless.
Oh, and not sure if it's a bug but the left analogue doesn't work for movement on my end, only the DPad. It's not something crucial though, just thought I'd mention it since it's listed as supported in the description.
Overall, I had a lot of fun :)
