i did kill the 41 enemies. and it was pretty fun once i figured out what to do.
a little confusing on the weapons, at first all i could do was fire rockets with right click, i did finally figure out to push q to switch main weapon and that allowed what seemed to be the rail gun to fire. i never did figure out how to get mini gun to fire, tutorial says hold for mini gun and just click for rail gun but that didnt work.
it seems like you have a larger scope in mind than what has been implemented. Id say for the live build to scale it back, dont even include the shop or whatever that was until you have it fleshed out more, just drop them into the demo level. The core of the game where you fly around and blow stuff up did fire some dopamine in me, it was fun.
the UI was very small and hard to read for me, i am guessing that it doesnt scale with monitor resolution so maybe check that.
I can see the vision but it seems like you have a lot of work to do before it is fully realized. have fun on your journey!
