As far as breakout clones go, this isn't a very good one. First of all, it could be prettier. MUCH prettier. Not only the sprites, the text font and colour is badly chosen, at times even unreadable. Music would be nice, too. There's no clear distinction between good and bad pickups. I saw no difference between the large paddle and small paddle pickups. Also, the lasers should move faster. The screen flip effect, however, was interesting and original, though it could last longer. The physics are flawed: sometimes the ball goes in a seemingly random direction it shouldn't, and sometimes it even goes straight through the paddle! Also, the paddle moves way too slowly. There seems to be no way to advance to level 2. I get the game over screen on top of the second stage with no way to close it but to return to the first. The first level is pretty well designed (I wouldn't know about the rest). Overall, 2/5.
Nice game. The character controls well but, when jumping, moving sideways is momentum-based, stops at peak height, and continues without momentum, which can be confusing. It would also be nicer if the boxes had mutual friction. The mechanic introduced in level 10 was hard to figure out and non-intuitive, though necessary for 2 or 3 of the levels. I like that the level design allows for you to be able to go to the same place but with different gravity without using the magic circle thingy. The music is nice but gets old after a while. The jumping sound effect is slightly unpleasant and the death one is underwhelming, but sound is otherwise great. Though simple, the graphics are enjoyable. The game runs very smoothly. The big problem with this game is the menu and options: they're not the best. There's no level selection screen and you can't turn sound and music off independently. The game's also too short and quite easy. Everything not mentioned feels good. I give this game 3/5 stars.
