So sloppy controls, pixel-perfect platforming and otherwise identical objects killing you or being the only safe place depending entirely on whim? Terrible.
Good game - challenging, keeps the new mechanics coming to push the bar up, simple but effective design... My only complaint is that it's way, way too long. This would have been great as a 5 or 10 minute game. As 30-plus, it's just a slog.
Pretty lousy, to be honest. The level scaling is poor, with most levels require minimal to no input at all from the player to finish. Except for the ones where the difficulty level increases and you didn't already buy the right weapons to prepare - then you're SOL with no real chance to stop it. There's no new challenges in the game that come up, with the difficult increase exclusively being bigger bags of HP charging after you. Some upgrades outright don't work (Lightning), while others are less effective than the previous upgrade and a giant waste of money (Shotgun).
There's no strategy, no variety and the challenge is extremely binary with no indications of when the poorly-scaled jumps in difficulty are coming. 2/5.
Water travels further. Airborne usually only infects in close proximity to whoever puts it into the air - further away than a couple of feet and it disperses into the air too widely, and it travels slowly. Water gets piped long distances and stays more concentrated.
