Wow! For a while, I thought I was playing on an NES emulator. The hard-as-nails progression, wimpy melee attack that requires precise timing, enemies respawning when just off screen, and flashing i-frames all come together for a wonderful and nostalgic experience with an impressive amount of content for for a Compo game.
What I like: * The graphics are awesome! The mouse looks cute and lively, the attack animation provides good feedback, the tileset is varied and provides some great mood, the backgrounds contribute to the theme, and the enemies are all well designed and fun. * An impressive amount of content! I was surprised when I saw 2 unique enemies, then I saw the third, and then a fourth! That's awesome for the time that you had. They're also all wonderfully varied and require different strategies to approach each. * The level design is great. It's linear but provides a great sense of progression through checkpoints, has a lot of horizontal and vertical elements, and a lot of fun ways to interact with the enemies. * Tight platformer controls. Not much more to say, a lot of people miss this. Bravo.
What I don't like: * Audio. The main music loop isn't terrible, and the death jingle is a nice touch, but overall it's kind of repetitive. Furthermore, a lack of sound effects for things like hitting, attacking, jumping, landing, dying, ect removes a layer of polish that would otherwise make the game feel even better to play.
This is an awesome entry. Well done and good luck with the competition.
