The game's definitely a good play. The protagonist is lovable, the controls are good, there's just a few tings that are wonky.
-There's something with the physics of the spinning wheel that makes it so BUG drops while he's on it, this prevents you from jumping in a timely fashion.
-The platforming is a bit clunky and frustrating. See if you can smooth out the controls a bit.
-The game has a bit of a problem of not being able to perform three functions at once (say, running jumping and firing at the same time) which is a pretty crucial task for defeating the end boss.
-The crushers and Tesla coils are placed in very dickish spots and very frustratingly spaced. I lost no lives to any of the enemies save the bossbot 4000 (mlgpro420blazit blah blah blah, heard it all before) but every life not lost on the boss was lost to a hazard.
Diagnosis: Controls and physics definitely need smoothing for platforming's sake. Tesla Coil and Crusher sequences either need to space the things out more or have save points directly after 'em. And for god's sake teach BUG to shoot upwards. <.< Don't let 'em suffer like Megaman did all those years. He deserves better.
