Sonic Dimensions, created by Phantom-Radea, is a high-speed Platform Game with elements from many games in the Sonic the Hedgehog series. As Sonic or Shadow, you are tasked with running and jumping through 7 action-packed stages note as quickly and stylishly as possible.
Sonic Dimensions contains the following tropes:
- Bonus Dungeon: Jungle Joyride isn't part of the main game, instead being unlocked for collecting all of the Red Rings from all 7 main stages. It isn't even accessible from the Hub Level, only being available in Time Attack mode. Trying to complete it without going Super is an exercise in pain.
- Double Jump: Mid-air tricks return from Sonic Advance 2, Sonic Rush, and Sonic Rush Adventure. Shadow's cover a greater distance than Sonic's.
- Expy: Shadow in this game is like Blaze from the Sonic Rush games, with inferior speed on the ground and superior mobility in the air when compared to Sonic.
- Hub Level: A Sonic Advance 3-esque overworld connects the levels. Omochao resides here to teach you about basic game mechanics.
- Gotta Catch 'Em All: Red Rings return from Sonic Colors. Collecting all 5 in a level earns you one of the Chaos Emeralds. Collecting all 35 from all 7 levels unlocks Jungle Joyride, which has 5 Red Rings of its own that can be collected for bragging rights.
- Ground Pound: Both Sonic and Shadow have a stomp move (from Sonic Unleashed) that enables them to stop suddenly in midair and hurtle towards the ground, smashing through enemies and weak floors along the way. Sonic's goes straigh down while Shadow's descends at a slight angle.
- Mooks, but no Bosses: Dr. Eggman is nowhere to be seen in this game. The trope is ultimately downplayed, as Mecha Sonic makes an appearance at the very end of Astral Station. So, the game has one boss fight.
- Nitro Boost: The Boost returns from the Sonic Rush games and Sonic Unleashed. It operates like the Boost in the latter game, being refilled by collecting rings and defeating enemies.
- Not Quite Flight: Sonic can only execute a midair dash once. Shadow can do it as much as he wants (though there's a short cooldown between air-dashes, during which he'll lose a little altitude, so he will have to touch the ground eventually).
- No Plot? No Problem!: No reason is given as to why Sonic and Shadow are blasting through the levels. You aren't even given an ending sequence upon clearing the final stage. But the gameplay's so awesome that the lack of a storyline doesn't hurt the experience in the slightest.
- Non-Indicative Title: No alternate dimensions or dimensional travel are involved in playing this game. Not that we can tell, anyways. It's not like there's a plot for it to fit into.
