Some things that I liked in order of most important to least important:
* The game felt pretty relaxing due to its sound track and gameplay. I didn't feel any pressure in the gameplay.
*The gameplay was pretty interesting. It was different and the gameplay felt pretty immersive as the player was given simple mechanics and there were multiple creative solutions the player could come up with those mechanics. I, for example, tried building stairs with bullets.
*The soundtrack was pretty interesting and not repetitive.
Some things that I disliked in order of most important to least important:
* I disliked the lack of a tutorial. Since there was not a proper tutorial, I was confused on how to know when to use the mechanics properly. For example, other than cosmetic differences, I do not understand the differences between bullet types.
* After a lot of bullets, the game could get pretty messy and this did not look nice. Sometimes, I might have accidentally surrounded myself by a bunch of bullets with no way to escape. The only solution I had was to keep on shooting until the level reloaded again so that the level would not have any more bullets.
* The controls were pretty strange and unusual. I particularly did not like using the Z and X button and I thought there were too many buttons in the game. It would have been better if there were less buttons so the player experience wouldn't feel so awkward.
* The UI, particularly at the main menu of the game, looks messy. The text is almost unreadable and this did not make me feel good.
