The one good part about this game is that the controls are relatively tight.

Hit detection is a joke. The sound effects are either royalty free or literally the Mario 1 UP noise. It's impossible to tell the difference between a wall that can and cannot be wall jumped. (This is only mostly true. SOME walljumpable walls are marked, but not all of them.) The amount of damage enemies do is seemingly unrelated to what they are. Stationary spikes are a heart and a half. Moving smashy spike columns are half a heart.

Some enemies will hurt you when you jump on them, but also take damage. It's impossible in many cases to tell when a cliff will lead to more level or will instantly kill you. It has a lives system with coins, but the lives and coins don't carry over between levels. The final boss gives you 100 bullets, but those bullets don't refresh between lives, though the final boss's health -does-. This game takes less than an hour to beat. Pursuant: I have, in fact, beaten the game.

The background art is pretty good, but the other tilework is terrible. Enemies can have the same sprite, but vastly different mechanics and different health. You have to manually select the next level after you beat a previous one.

The 'beat the game' art is actually worse than the title screen graphic. Of the guns you can get, one of them is an actual upgrade, and one of them shoots three shots (which you will never need) for three times the ammunition, which is acceptably sparse to begin with except for when you get a million ammo in areas with like three enemies.

The box physics are horrendous. In one level, I pushed a box down a thin shaft, and it got stuck halfway. Boxes on moving platforms will skitter around like nervous squirrels, and none of the puzzles are interesting enough to merit there even being box-pushing in the first place.

There's an enemy that is basically a koopa troopa, but not a single level ever puts you in a situation to use this to your advantage, or against you. It's there just for the sake of being there.

TL;DR Quite literally everything in this game that is not 'controlling Super Mustache' is achingly bad.
