I'm really impressed with the presentation of this game! The opening cutscene is really great, and I particularly like the art style for the game. The backgrounds look really fantastic! I read that ya'll plan to keep working on this and I look forward to seeing that.
Two biggest pieces of feedback I have are I had a lot of trouble with the enemies and platforming. You can't aim the projectile attack, and the ground enemies are so low to the ground that you can't really hit them with either attack.
There are also quite a few sections where you jump into a screen transition, and you can't see the platform you're supposed to be landing on. This corner was particularly tough for me because you have the spikes enemy, and then a tiny red mosquito is ready for you right after the transition.
Awesome job!

Thanks so much for your kind words — it really means a lot to hear that you enjoyed the presentation, especially the cutscene and art style!
We actually had a lot more ideas and plans for this game, but due to time constraints we weren’t able to implement everything we wanted. I really hope we’ll get a chance to come back to the project and continue working on it.
