Pretty cool game, nice graphics and very polished. I did find a bug, where I started to not get any damage, probably something with the iframes. Also, it would be nice to change the shop icon, to an actual shop icon or something like that, because on my first playthrough I didn't even know it had a shop, also, allowing to gamble all the money could've been fun, instead of only allowing 10 - 50 increments.
Overall a pretty cool and solid game, very good potential.
