This was a fun challenge! I really enjoyed planning out my route and taking down each UFO (the stock explosion sound effect is amazing too). The misfire mechanic was pretty annoying since there was no feedback in the game when it happened, I was suddenly just not able to shoot anymore. It wasn't until after beating the game and reading the description that I understood that each bullet got more powerful the lower the count was and that there was a chance for a misfire. It might also be nice to have the game just a bit more zoomed out. Overall these are small nitpicks for a very fun game that I enjoyed a lot! The spritework and the CRT style filter was very nice too. Seriously good job on this!
