OMG, bro I loved this game, the physics, although they have some bugs, I like them a lot, it seemed like a very, very fun game, I was playing for so long that I reached the end and discovered that with R I could reload, then I was amused because in the In the game page I thought it said something about the controls, but I was very amused that at the end it said "LIMITED Ammo" XDDDD, anyway they were very good, the final level obviously they made it to be almost impossible, but the walls are so thin that with enough speed you can get through and once you are out of the level shoot and R until you get to the end, but it was very sad when at the end there was really no way to go to the "YOU WON" screen would have been great, That's when I realized that this level was not made to be finished XD, anyway, I think the game has a lot of potential and you could create some Challenges, such as passing it with the best number of bullets possible, or in the shortest time possible It would be very interesting, anyway, thanks for creating such a fun game.
Some tips to keep in mind would be that the Quit button is away from the center of the screen, so that it is not so easy to accidentally press it instead of Restart, another thing is that the gun on some occasions stopped following the mouse pointer and I had to get it really close to the gun to get it to work properly again, that's all.
Here I leave some evidence of me floating in the void the first time and me at the end of the last level waiting for a "You won" message 😭
