Players play as construction worker Jack Hammer who is aiming to defeat Doctor Moonbeam in his bid to "turn the world into a sugar lump to put in his cup of tea".[5] Players use Jack's large hammer to destroy the buildings of Timmy World under a time limit, gaining Timmy Points by hoovering up the Timmies released from destroyed structures to purchase weapon upgrades in the Hammer Shop.[6][5] The game includes Quest, Battle and Arcade modes, the latter of which supports up to four players.[7][1]
The game received a poor critical reception. Iain White of Saturn Power magazine gave a score of 51%, describing the title as "slow-moving, badly designed and utterly utterly tedious" and decrying its "blocky looking graphics".[7]Sega Saturn Magazine's Gary Cutlack was even more damning, offering a score of 38%, noting that while "the idea of destroying stuff with a hammer sounds cool...the gameplay is dull beyond belief", and criticising the "very rough, very brown, very dull" graphics and "samey and uninspired levels".[6]
Reviewing the PlayStation release Play's Tom Sargent labelled Trash It as an "unusual puzzle-come-platform game" that "plays too sluggishly and becomes repetitive far too soon...a 16-bit game at a 32-bit price".[1]
