I have some suggestions. First off I think it'd be cool if you could give us the feature to save our times in-game so we don't have to write it down somewhere. Also it'd be cool if you have in the options a way to turn off that red dot when grappling. You could also add it where you can pick up things even with the gun in your hand. Also like what someone else said different gun noises for each gun (doesn't have to be vastly different but just a little). Some ideas for levels could be like a sci fi themed with space guns and space like things. Maybe some weird gravity things and alien monsters. Also where your level selection you could add like a way where levels are different worlds (like mario). So for example you click an arrow to go to the sky levels ect. Another idea for some levels could be where there is 0 lighting except for the platforms which are like neon green and you can't see the monsters so you have to try and guess where they are by the direction of the bullets. Plus please add more grappling levels those are honestly really fun. Keep up the great work! Looking forward to the creating maps aspect if you can get it working! Plus one more suggestion when you get it on steam you should add it where we can compete with our friends to get better times or something of the sort.
