...Dimps is unable to make a classic Sonic game. This isn't up for debate, they cannot get the job done. In Sonic Generations for the 3ds, they just copied the levels from the classic games then gave Classic Sonic the homing attack because they couldn't design levels without it. Likewise, Sonic Advance had Sonic Team staff in the programming department specifically the oversight of Yuji Naka. Again, this is not up for debate as even M2 needed his help with the porting jobs (specifically the adding of the Spindash to Sonic 1). Interview here I bring this up because as anyone will tell you, Sonic 4 isn't Sonic 4. Sure you can look at the metacritic rating but the hard truth of the matter is that not all opinions stand the test of time. Where are those critics now? Gone never to be heard from again. Us fans, we are here for the long haul, we remember and we suffer when screw ups like this happens. Even if this game was called "Sonic the Portable" as initially claimed (this game came out before Sonic Colors which was aimed at Modern audiences), this is still the game they wanted to entice the Classic Audience with. Just let that thought linger for awhile. Episode one is a rehash. This is by design. The graphics are ugly, the physics don't work, springs may get you killed as you are launched over a gap if you aren't holding down left/right (depending of which direction you are launched), there are sections built specifically for phone tilt controls that are just horrible, Dimps standard death pit at the end of the level nonsense, bosses range from non-threat to cheap instakill BS (looking at you Death Egg Robot), and I think Jun Senoue misses his guitar. The only good thing I can state is I like the special stages but even then that is more to Sonic 1's credit than this game. I cannot recommend this game in any serious capacity other than as an example of what not to do. Episode two is barely passable as classic Sonic game. The graphics are still ugly, the physics are a little bit better but still don't work, level design got worse due to the addition of Tails (more on that later), they didn't give us elemental shields but instead some terrible clear the screen nonsense item, bosses are a mixed bag, they bring back Little Planet but do nothing with it (or the time stones), and Jun seriously needs to get his guitar back. The Oil Desert theme is clearly a cry for help. What really hurts this game is Tails or rather areas that require flight/swimming. These sections are lazy in that the design is so inorganic that they need to place monitors to tell you what to do. The monitors are fine in say the first zone but after that, they are just overcompensating for bad level design. Hell, they made the worse scrolling plane level in Sonic history by adding a death pit platforming section where enemies fire projectiles at you. And then there is the addition of the Boost. They call it the Rolling Combo but it is just the boost. Same excessive forward momentum, same semi-super Sonic invincibility, only now it is more broken in that you don't need to build meter. It is useless, only comes into play with special walls to break. Sigh, they couldn't make episode one without the homing attack, now they can't have episode two without the boost. Lastly, there is the final boss which has an amazing design both visually and gameplay wise...Shame I can just cheese it with Tails. To sum up Sonic 4, this is the culmination of years of speed based game development coming full circle. Dimps only makes portable tie-in to Sonic Team games instead of original stuff, Whitehead's Sonic CD came out and reminded everyone what Classic Sonic actually is. The critics turned but they never cared about Sonic 4 to begin with. Episode 3 got cancelled due to low sales and the name "Sonic the Hedgehog 4" is forever tarnished...Well, the Modern Sonic 4 is forever tarnished, Classic Sonic 4 could still be good.
