You have an eight directional dash so you can dash upwards which acts as a double jump. There are 3 levels after the tutorial. In the levels after the tutorial there is a void that chases the player and if you stop moving it will catch up to you and the player will get captured by the void.
Really fun game. It felt so satisfying to reach a point where your bullet starts shooting a bunch of small bullets and you start defeating all enemy's really easily. The upgrades and variety of them made it really enjoyable to learn how the game works.
I liked the jokes in the game and the movement and attacking easy to learn and use. I think you might have made the boss a bit too strong though. Other than that it was enjoyable.
I enjoyed the gameplay, I like how there is multiple enemy types you can find which adds a lot of replayability. The graphics of the game look really good and the sound design is also nice. What was your hi-score?
