Dont burn yourself, and dont put yourself down. Sure you saw flaws, what person would see them? Everyone strives perfection and sometimes will see an oppertunity to improve what they already released. No biggie. The whole thing revolves around you, this is your brain child that you want to see to completion!
From what I saw in your title, its pretty damn good! Take your time, enjoy what you do. You see some flaws, fix em when your ready. Seen alot of great potential in titles that the DEVs got burnt out and abandoned them all together and were never seen from again.
Chill, game, enjoy!
