Its like a train robbery with ramps in the wild west in another dimension.
The player movement and physics feel good and the mech animation and vfx feel alive. The bullets being simulated gives it the final touch to feel like a simulator. A good foundation to add stuff like a target lead indicator, which would fit the theme.
Once you get it, it's to easy. The target could have guns like flaks on airplane carrier, which lead shoot you, so you have to change course regulary. This gives good scalable difficulty.
There may be some control hiccups, pitfalls, too loud enemies and imbalances like reloading time, but overall this is a very good execution for a complex project like this for the jam.
The coloring, mech model, music, fx and action fit very well together and give a smooth experience.
