Glitches

Getting more than 9 dynamite charges

10 dynamite charges in inventory

Dynamite charge pickups only respawn when your amount of charges is 0.
However in "Level 3: Train 2" you can collect a lot dynamite charges throughout the level. Then near the end of the level there will be a dynamite throwing enemy which will spawn a dynamite charge each time you kill him. When you collect that charge and die after that this enemy will respawn. This way you can collect more dynamite until you run out of lifes.
The onliest effect of having more than 9 dynamite charges is that the number will overlap a small part of the Dollar symbol in your inventory. That indicates that you weren't meant to get a two digits amount of dynamite.

Level 3: Dollar Rain Glitch

When you defeat the sub boss in Level 3 there will be a Dollar rain for a short while. When you die after defeating the boss and before the rain has finished you can run from the last checkpoint back to the boss and watch the rain from the side. You can not proceed earlier than usually though.

Level 3: Soft Lock after 2nd boss

You can lock the game after the final boss in Level 3. To do so you need a few dynamite charges in your inventory.
After defeating the boss you will loose control, but you can still place dynamite on the ground. If you do it in the right moment you can cancel the celebration dance and thus prevent the game from continuing. You will then be locked on the train.
