This reminds me of another game called the Binding of Isaac. The explanation about hearts, upgrades, and pixel themed. They had similarities on impression. Will take a look at the gameplay on youtube to see what's up. Awesome job on the review post. There are really too few people that dedicate a lot of effort creating a comprehensive review on subjects they are passionate about here. I'm also a gamer so game reviews are always something I look forward to. :D
