Really nice Megaman inspired entry, tiles looks fantastic, having different weapons is obviously a must (but I did not end up using them that much), there is a lot of different enemies and details put into every level!
The only bad things I could say is that the camera in the "Botanical Garden" sometimes hides crucial parts of the level that instantly kill you and the appear/disappear platforms go on/off instantly (even in the Megaman games they at least had an appearing animation if I remember correctly).
But this are mostly nitpicks, incredibly neat game and amazing entry!!
