Update after the major patch: There are more rooms now that rarely repeat. Although barrels and conveyer belts add details to the room, they still feel a bit empty. However, you don't spend a lot of time in them because gameplay is still fast. New addition are trap rooms with flying saws, but these are very easy to dodge.
New stages and characters are also welcome; now there are only five stages with an end boss so you can't loop the game forever. The only problematic might be the last stage; it has a weird pattern on the floor that makes my eyes hurt. Success still depends on luck and items still don't have information about what they do.
Although shooting works fine, the game has basic rooms, only a few enemy types, and powerful items.
You can select from a variety of characters, each having a unique weapon as well as damage, health, and other stats. Of course, you can only select the basic character first because everyone else is locked. Although some seem different, they all play the same way. The only controls you need are movement, dash, and the left mouse button to fire.
Each run starts with a random object. These items provide a variety of benefits, like faster firing speed, more damage, and many other features present in any similar game. The game takes you through enemy encounters that take place in an empty square room. Enemies can drop both coins and health.
After you've defeated all enemies, you can enter the door to the next random room. The rooms aren't exactly random because they're chosen from a list of pre-determined rooms. This means you will encounter the same rooms multiple times throughout the same run.
After the tenth room, you receive another random item or a weapon to make things a little easier. You may also find yourself in a shop where you can purchase items with coins. Because one enemy may be grinded for health and coins, the game avoids this by limiting the number of coins you can carry.
You'll need everything you can find since the game is difficult. There are numerous different enemies, and they all move quickly. Death often feels cheap because fast enemies drain all of your health through contact damage. Another major issue is health and energy canisters, which give all enemies healing and faster attacks. You have limited options until the canisters are destroyed.
On the other hand, it’s possible to break the game with powerful items. One of the best things you can get are ghost bullets that go through everything. Because you can fire through walls, most rooms become extremely easy trials. And when I added auto-cannon, machine-gun perk, and damage, I cleared a room in seconds.
However, this can be ruined in rare cases if you take a new item. The problem is that you don't know what the item does, and new items always comes first. For example, a new but inferior double-bullet perk can replace the old but extremely beneficial machine-gun perk.
At round 20, a boss awaits. When you defeat it and enter the elevator, you will respawn in a different location, although the rooms will have the same enemy patterns. You can keep going for as long as you can because the locations will loop. However, you can end the run by killing the shopkeeper and getting a tape that transports you to a secret boss.
Compared to similar games, this one is overpriced for the stuff it offers. The graphics are simple and monotonous, there are no "meta" upgrades, and shooting can be broken with overpowered items.
