Cool game! I like how you added hidden message on two levels!
Suggestions ->
- Add arrow-keys support
- I like how you used just simple shapes for your game! You can spice things up a bit by adding more colors. Using a different color for the environment will help the player stand out more, just like how you used different colors for the enemies.
- Add an option to skip typewritting effect and show the full message with the space key
- There is no point in showing the upgrade menu just after the first level, I didn't know much about the game at that time so I couldn't tell which upgrade would be useful. You can unlock the upgrades after a few levels when the player gets to know more about the game
- Tell the player about the control keys to respawn and dash, during the gameplay.
- I couldn't tell much about what was happening in the level with the enemies, you can add some helpful text for that level
- The player should be able to restart from the level they died in instead of the starting from the beginning
Bug -> The dialogue messes up and shows the whole dialogue for a frame before starting the typewritting effect.
