This game was actually really cool!
Bugs I experinced:
On my first playthrough I touched a bat or something happened where my player sprite flipped upside down I wasn't able to recreate it but the player still worked fine despite the asset being flipped.
During my second playthrough I noticed that I was gaining velocity along with my bullets as long as I survived and held space I could keep gaining speed which I don't think is intended.
The skeleton enemy spawns bones in a pattern which was cool and fits the theme pretty nicely but when I killed a skeleton that already had bones spawned the bones still shot out unsure if bug or feature.
Things I liked:
It took me until my 2nd playthrough to understand that if I stand in a color it slowly makes that choice and enemy deaths will drop either green or purple 'blood' to change the stage which is super cool way to change it up.
Art assets were simple but felt a bit out of place given the rest of the style of the game I understand this is just a sprite pack but I don't think they fit the games stage well. and the music was decent enough where it wasn't too repetitive to be annoying but still catchy.
Things I wanted:
I was wishing for diagonal shooting without having to move diagonal given the nature of the movement there were lots of times where I was just off a few pixels from shooting an enemy and id have to readjust, which could be a feature or not but I found it somewhat hard to hit enemies.
I was hoping to know if a enemy was purple or green but had no good way to know, maybe I missed something but having that info would have been nice.
All around this game was fun simple and fit the jam theme well done on pushing out a game for the jam!
