Enjoyable, with only a few personal gripes.
Super Puzzle Platformer is a game that I would indeed revisit every once in a while for it's charm, it's addictiveness, and it's music. However...if a sequel is in the works, a double jump feature would be liked (though it may be game breaking, seeing as you were to craft using only what you had, which was an enjoyable challenge), and I personally would like a larger screen, different gun types...just more additions to the core gameplay in general without making it different. Oh, and WASD controls so one handed playability would be there.
...Overall, the game is very fine tuned, very addictive, the controls are great (with the exception of jumping, which felt more like a tumble through the air). I also would like to see a gun aiming kinda thing going on, like in Cave Story. Often times I would wish that I could aim my gun below me to destroy a connecting spike...but only to find that I couldn't, and I had to wait.
...It's a good game, but a few more tweaks here and there would be amazing. Thank you.
