ok, so i finished working on my second game (called 'figura climax'), it's inspired by old simple 'hi-score' based nes games. i'd pretty much like to hear your opinions about everything, music, artstyle, mechanics - so i can improve in those areas for my third game.

It's pretty neat.  Are there weapon upgrades?

sadly no, nothing of that kind. for my second game i mostly focused on polish and responsive gameplay/visuals.

One thing I did like about your game was the shooting mechanic. I noticed that when I pressed the mouse button the gun was juuust about the fire but then no.  Then I clicked the button a bunch and the gun tried again to fire but it just wasn't working.  It was then I realise, ah ha, I have to hold the mouse button down and then it will fire.

yup, i did that to prevent mouse spamming. glad you liked it.
