Oh boy Game Maker 8 Lite.. what a nostalgia! That's what i started with. I don't know how you could manage to fit 2 different levels and different gameplays and a boss fight in 2 weeks but. WELL DONE! I liked the first level much better i think. Having the mouse click as a shoot button would be nice because my thumb got tired after little a while. I like the aliens and how they squish but they squish too much in my opinion. Cover art is really nice too! I suggest you to not use the built-in score variable and use your own variable instead this way you have more control over it. And seeing the score on the screen would be nice too.I mistakenly found the 'F' button, i think you used this to test and debug. I couldn't beat the boss so i cheated a little with that :D This is the second submission i'm trying and i cheated in both of them i don't know 🤷♂️
