True bundle fodder, it's been bundled several times, and even the programmer has refused to make the achievements work. It's a messy game with a neat idea but awkward physics and controls. The graphics are just not engaging, just like the "platforming". I like the fact that precision jumping is not required, but mostly because precision is impossible with a ball of tar. Gameplay is repetitive along with the music, the same 3 enemies are recycled through the game. The game is just so bland, and really didn't age well. The Lives system is just old and awkward, you lose lives for saving to quit! Despite finding many issues with The Binding of Isaac, at least that game has polish and a bit more variety, recycling a massive 15 enemy designs instead of 3.
The game is just not engaging, even the programmer doesn't want to bother with the game to make it match what is advertised in the store. It's not a "must play", it doesn't do much noteworthy. I wouldn't bother with it.
