Other than that your graphics look amazing, absolutely professional. I'm really curious how you create them?
hey thanks i cheated! only a bit

for my character i used the free tool at http://www.famitsu.com/freegame/tool/chibi/index2.html
i bet no one get that my avatar is actually a she
for the walls i created one block and done all wall graphics out of this little block
the slime was done with nice samples i found on google and deviantart
and finally the coin was a free to use sprite without any licensing so i only slightly modified it

deviantart and sometimes google is a nice way to research for art (there are many more nice art communitys out there)
