What did this game do well? (Answer in a few sentences)

• I like the game feel/ When the player gets attacked. the whole screen shakes.
• Game sound is well done, the small sprite animation, level generation, and the ai for the enemy. Is very intuitive to play.
• I really liked the procedural generation made each game feel fresh. I liked the concept of the enemies, it added a good challenge. I liked the death animation. 
• The goal is clear and the game is intense. 
• 1) When I died, I didn't feel sad but laughed out loud. WHAT A FUNNY ANIMATION HAHAHAHA! 2) Very appropriate increase in difficulty. In level 1, there is no enemy, giving player a change to get familiar with control. It's like a tutorial level, really good design.

What could be done better? (Answer in a few sentences)

• Sometimes for some reason the enemies disappear after I reset but this should be fixed easily I guess.
• 1) Only one problem I find now: sometimes the enemy and crystals may be in the same place. When I try to eat that crystal, I would lose HP. 
• The player controllers could be a bit tighter or have more acceleration to it. Different enemy types or a way to defeat enemies could be a good add. Sometimes enemies are in a spot where it is impossible to not get hit. 
• The enemy can be a bit bigger
• Could have maybe turned the currency that you pick up to powerup your character or different enemy mechanic, but otherwise good game.
