I’d never seen this game before, so let’s turn the description duties over to the Retronauts team:

What’s this? A horizontally-scrolling sci-fi shooting game, originally developed by Allumer iand distributed on arcades n 1991 and reissued for the first time via Arcade Archives in 2023; ; players fly an R-Type-esque spacecraft through R-Type-esque stages on a mission to destroy a bunch of R-Type-esque biomechanical monstrosities, with the aid of a pair of arm-shaped appendages attached to the top and bottom of the ship that undulate with the movement of the ship and can fire angled aim shots and block enemy bullets (unlike R-Type, but not entirely unlike sister game X-Multiply.)
