This is a fun little game that offers interesting ways to work through levels, but it gets frustrating with dark levels that require trial and error.
You can complete the game just fine, but unfortunately the experimental blue boss is truly bugged. It soft locks on stage 3.
Other than that, this was an enjoyable experience.
RIP Francisco Munguía Villalta; your art made us laugh and made Newgrounds just that much brighter. You will always be missed.
