Really cool blend of ideas here,
I like how this is kind of psychonauts meets shmup gameplay, so un unexpected mix but that works quite well.
Some small negative aspects, i'd say that there is a bit of a lack of feedback when the player gets hit or not, and i didn't really see where health was displayed cause i got hit a few times but i was able to continue, yet i didn't know how much hp i had, also no autofire and having to spam click the gun wasn't that great, also sad that there didn't seem to be any weapon powerups to add more variety.
Now that said the game is fun to play and has some really cool artwork, i knew i recognised that artstyle, cause i remember playing another game of yours on a past jam and this gave me the same miyazaki inspired vibe on character design as your mech pilot did :)
Overall had a good time playing through, good job ^^
