I´m not able to try this game yet :(

Good work on the retro vibe here, always nice to see. The player character feels nice to control as well, very smooth, and I like the details here, like the enemies flashing white when they take a hit is some good visual feedback. I noticed at times when I killed them though, I would boost right up into the roof. Not sure if this is intended, but it didnt seem that consistant to me, could be neat to have that happen every 3-4 kills though, so you can use the boosted jump to really progress through the level. 

A short but nice platforming game! I noticed that you can get launched up really really high if you jump up against an enemy instead of landing on them from above, which was pretty fun to do.

Good job on finishing!
