Wow! Surprisingly! That was really really fun! I mean you nailed the gameplay. I would say you nailed what actually makes a game good so 85% of the work in making this a 5/5 game is done. I understand the limitations but I would say, if you make a game with shapes again, Just use some bloom. You have particle effects but if you combine that with bloom too, you get an amazing game that looks amazing too. Music needs work but even I spent hours and hours on music and couldn't do much. I understand it's really difficult to nail the music but really, there are just the nitpicks. You did an amazing job. It was a fun game with a brilliant boss fight! Thanks for this game! Had an amazing time!
