Sweet game! The first thing I noticed was it has a lot of charm and character! The color palette is very nice and refreshing! The gameplay is really solid but it is incomplete in a few places. I am not sure where you plan to take this but it would be great to have upgrades when you fill up the level-up bar. It wasn't clear to me you could go behind building at first but I think that is a nice touch! The bat didn't really do a lot of damage and once you ran out of bullets there was no way to get more. It took me a while to notice the EXP bar and when I filled it up it just kept going haha. I would have also liked some music! You have a great start here and I hope you will keep anding to it!
