This is a great game! The Pixelart is absolutely beautiful and stunning, especially the opening scene and I love how the color of the background changes everytime you die, it really helps with keeping things fresh. The controls are simple and intuitive, however the fake Loading Screen was a bit confusing at first.
The core gameplay was good, but I think it could've been improve. It feels strange how you have to go back and forth between rooms just to hope that your desired level you need will spawn. After you finished and getting the key, you have to repeat this process over again until you can claim your bug, then go to a single room with all the power ups
just to the whole thing all over again, which can get very boring. Perhaps you could add a main roam with different rooms connecting to it and unlocking the upgrades more progressively?
Also, in order to use your abilities, you have to use your charges, which I don't like and feels very unnecessary. Since those are very easily obtainable, they dont really add anything to the gameplay, but if you don't have any left you have to go back and get some which really destroys the game's flow (and repeating the boring room-cycles isn't very fun). I think optional collectables similar to the strawberries from the game Celeste would've been better and getting rid of the charges entirely. Also, I've found it weird how the character doesen't fit into 1 block gaps like those in the laser-maze room.
The SFX and especially the music are very well done and fit to the theme perfectly, which itself is very good!
Overall, a very solid game! I loved it, keep going!
