This game is a load of fun and made me feel like a million bucks! I like it being a Warioware-esque game which makes it one of the more unique entries here, the minigames themselves being mini-references to other games is very flavourful considering this game's Warioware-inspiration (aka the same happening in Warioware itself, too!), the fact that you can customize your arcade-cabinet is just flat-out adorable!
There could have been a little bit more variety to the minigames, at least in the pattern-sense (the bullets in the Undertale-heart-dodging coming after the heart randomly). But considering that you have practically made five games in one (the game itself and each of the minigames being counted separately ~) and there surely having been time-constraints, I can't knock on you for that too much now can I ~
The music and the action speeding up does remedy this! And again, very flavourful to the original Warioware! And the music is diverse, pretty and cool! And the music getting distorted as you lose a life is flavourful, again :D , and cool!
Overall, impressive! Wonderful!
