This game follows an interesting take on the standard aim and shoot also implementing movement and certain tough jumps into the mix. However, it doesn't feel that smooth or enjoyable to play as of right now.
There isn't a whole lot of texturing, the title screen is just buttons, there's no background music or anything. The file size seems a bit extreme but I don't know the specifics of what's in the game. The grappling hook doesn't work if you're moving too fast or if you jump before hand (tested this a few times on the tutorial level and it just wouldn't let me grapple).
Overall this game needs a good amount of work put into it because it seems there's quite a lot of issues with it. Also maybe there could be some form of cosmetics system where you can get skins for the cylinder like a toxic waste barrel, explosive barrel or just various colours for the cylinder.
