I really wanted Solar Max to be fun, because its art style and soundtrack is wonderful: I'm a sucker for pixel art and chiptunes, and this features great examples of both.
The core idea of Solar Max is cool too. You float around space, trying to find air tanks, to refill your oxygen levels and continue playing for longer.
But the gameplay just isn't there. Items are too small to pick up with any regularity, and there's no radar to see where the next pick up that you should be headed to is located. On top of that, the jet pack you're using is ineffective at turning and guiding your hero in the cold gravity-free environment of space.
Here's Solar Max in motion.
