As a Unity developer I definitely recommend making a web build since web builds make it easier for people to play, and making a web build in Unity is very easy as you go into build settings and switch the build from windows to web/HTML.  Other than that, the game is fun overall and as others have said it has a unique 90's/00's feel. Good job :)

Not sure what was going on, but when the game started, I couldn't interact with any of the weapons, which means I couldn't shoot or anything. Randomly a jetpack appeared on the players back but I couldn't do anything with that either. The game seemed pretty ambitious though. Liked how it had the intro cutscene and the pop ups with the enemy and the objective. Just wish it would have worked. Even closed out and restarted to try it. Another thing to note is the need to download and install is a bit much. I don't mind downloading games, but needing to install always feels so intrusive. I'd recommend focusing on web builds in the future! 

What an amazing game, visually stunning and great fun to play, good job!

This game is so well done! It has a nostalgic feel, the camera movement during cutscenes is well done. Reminds me of N64 OOT or MM in terms of cinematography. And that this was done in 9 days is really good. The interaction with items was a bit difficult, had to get the right angle to get the items and some indication that you are in range of interaction would have helped. I would have loved a minimap too I got lost (there's always someone amiright?).  The fights needed tuning because I could just kill every enemy with ranged weapons, close range was tricky to hit the enemies. It wasn't clear when I hit them (having them light up in red or some visual indication that the attacks hit would have helped). I am just nitpicking though because I thoroughly enjoyed this :D 

Probably the most ambitious game I have played so far and you executed it very well. You really made a complete narrative mech combat game with a boss in this time span. I love all the graphics, it's my favorite retro era and I think you captured it very well. I like how in the bit of dialogue there was you did good world building. Under the game you list dash as shift but I didn't seem to get that working, maneuvering without it was a bit long. I could cheese a bit of the game with the pistols as they didn't seem to have a max range, so i could hit from across the map. Overall great job!
