Loved it! The model looked pretty cool and retro. (stealing this) The flying felt great while in the air. The laser cannon felt good to use. I liked the robotic "power up" as you activate your crystal ability. The denizens of the world are weird and round which indicates to me they just want peace but you're coming in and screwing it all up, by taking their precious crystals. Boss fight was cool addition and was kinda tough. UI was minimal and well done. Great water shader!

I think for the flying I would have appreciated a way to descend quickly. Felt like I had a lot of control in every other direction except down. I could kinda boost down sort of? But a straight down option would have felt awesome. The pickup areas felt like they were too "small", I had to really get on top of them to pick them up, the movement which is great for everything else is too "floaty" to accurately run over them. Left cannon projectile speed I think might need a bit more tweaking. Leading shots wasn't difficult, but it kinda just took a while to get there I guess? I know it gets weird as you increase projectile speed, but with how large the models are I don't think you should have a problem. 

Music was calming and further contributed to my head cannon that the creatures of the planer are supposed to be peaceful. SFX I think fit really well here. The rockets and gun sfx all worked well. The only one I wasn't a fan of was the getting close to death SFX. The buzzing was not my favorite.

Great job getting this done in a Week. Mech Gang Rise Up.
