A really good first step into making a game like this! The controls, and especially the jump, felt really nice to use! And being able to just mash the gun fire with enter and shift was really satisfying to me personally! A neat leveling up system to allow for a bit of customization and multiple weapons to choose from all made for a neat little package!
Only a few nitpicks from me, like jumping into the side of walls had some weird interactions. Using the mouse to select level ups is a bit odd. The worms looks cute but a touch out of place. And perhaps adjusting the level design to be a bit less backtrack.
But overall a great start! I could see this being expanded upon into something really fun and engaging!
