I must say, when I saw the art I wasn't expecting this game to be great. But I was wrong. I enjoyed this one so much! It was very fun to upgrade the ship to go further next time and it didn't get boring in the time it took to beat the game. It was great to try to get more money to figure out what the saw and booster were and they were really fun to use haha. I think it would have been good to ramp up the difficulty over time, maybe introduce different types of enemies as you go farther, also maybe make the enemies' movement patterns a bit more predictable. I also stayed near the top of the screen for most of the game since in the edges there's less enemies to dodge from, so it would have been nice to have something like temporary powerups you get in the middle of a run to incentivize you to move around more to get them and also would introduce a bit more variety. With some of those improvements and also visual improvements this would be a really solid game and it was already a very fun experience :)
Edit: It would also have been nice to have a Linux build, I had to add the game to steam and run through proton to be able to play, so it would be convenient if i didn't have to go through that whole process haha
