Three stars for the random names alone... "French Dick Woman", "Islamic Snowboarding Simulation"...awesome :)
Too slow to start off though imho, if you don't use an autoclicker.
More bugs: Knockback + high attack speed can knock mobs (especially ????) out of bounds and you have to Exit Dungeon. / Very often on using the mirror the game stalls and you have to reload (probably when using the mirror before an internal script is done). / Locking screen -> "Application lost device context" which is a showstopper for an idle game for people that run them at work.
If you lock your screen while the game runs or the UAC activates for whatever reason, the game breaks with error: "The application lost the device context!" (Firefox 42.0 on Win7 64bit).
Good novel idea, but it needs balance and some more things to do to engage players. Compare to the higher rated idlers (remove the graphics and think what is left).
Thank you for the very constructive feedback - we are working to release a sequel which we hope will be a much better and more interactive version of Idle Racer 1.
Usable base to expand on. Needs plenty more things to do in terms of upgrades etc, maybe different types of drop size (drop, blob, balloon...) as multipliers, also achievements and the obligatory "soft reset to gain bonuses on the next game". Check high-rated idle games for ideas on what's missing here. Currently it is not engaging enough.
You definitely need to make the game area smaller and find a better way to put the upgrades in without having to switch between a dozen screens.
The upgrades need to show how many of them you have already bought.
The upgrade scrolling, while nicely implemented (not scrolling the whole page, only the upgrade buttons), is way too slow - make it scroll 10 times faster.
Also revisit the balance of price vs. reward; if it goes too slow, people will watch paint dry instead, if it is too fast, it gets un-engaging quickly. Look at Strength, Iron Pickaxe and Heat Armor, they seem pretty unbalanced imo.
And most important don't get demotivated by harsh comments...every developer has a "first release" someday. :)
Needs proper idling/offline support. When the tab is out of focus, it does not go on but accumulates shots, killing one wall when you go back to it. When offline...?
