What are you talking about your game is pretty well done with a cool concept!!!
There's no way this game would get last place: sure it won't be the best, I won't deny it, but it certainly isn't the worst…
Also, it's hard as hell to do a bugless, flawless game alone: even people that work in a team aren't safe from bugs. Don't let bugs discourage you: it's only part of the learning process…
(And personally, i love finding flaws in games, even if sometimes can result in some harsh comments. So, for me at least, it's a 50/50, really...) =D
Btw what is the map for??? The game can be playied fine whitout it, and maybe it's even more fun that way... (But this can be easly just me...)
