“Yes but also, no. I really want to like this but its so punishing and not in an enjoyable way. Each time you die, even if you hit a check point your ammunition and consumables dont save. So every time you die even after…”
“The Thing + Carrion + Barotrauma = Hidden Deep A near perfect horror experience of the unknown & the costs it takes to survive in an environment man was never meant to go to... 9/10 -1 point for the occasional annoying…”

“Genuinely liked playing through this game and the gamemodes, the controls felt like playing one of those old flash games. Its quite difficult to get used to though because of how good the physics system feels honestly.…”

“I want to like this game but the controls and lack of explanation on its controls is a massive pain*. For an example, trying to fight an enemy that gets too close is awful. You can't really shoot the enemy as its in…”
“If you love these old school 2D platformers you won't go far wrong here. The physics are decent, shooting feels impactful and the various gadgets and vehicles are great. I felt the level aesthetic needed more variety,…”
“janky and friendly fire is super obnoxious with the 2d element, basically limits one person only to handling hordes or else you'll nail your friend in the back”
